+
+	  This code has a reasonably generic interface so that similar
+	  control registers on other processors can be easily supported
+	  as well:
+
+	  The Cyrix 6x86, 6x86MX and M II processors have Address Range
+	  Registers (ARRs) which provide a similar functionality to MTRRs. For
+	  these, the ARRs are used to emulate the MTRRs.
+	  The AMD K6-2 (stepping 8 and above) and K6-3 processors have two
+	  MTRRs. The Centaur C6 (WinChip) has 8 MCRs, allowing
+	  write-combining. All of these processors are supported by this code
+	  and it makes sense to say Y here if you have one of them.
+
+	  Saying Y here also fixes a problem with buggy SMP BIOSes which only
+	  set the MTRRs for the boot CPU and not for the secondary CPUs. This
+	  can lead to all sorts of problems, so it's good to say Y here.

+	  APM is a BIOS specification for saving power using several different
+	  techniques. This is mostly useful for battery powered laptops with
+	  APM compliant BIOSes. If you say Y here, the system time will be
+	  reset after a RESUME operation, the /proc/apm device will provide
+	  battery status information, and user-space programs will receive
+	  notification of APM "events" (e.g. battery status change).
+
+	  If you select "Y" here, you can disable actual use of the APM
+	  BIOS by passing the "apm=off" option to the kernel at boot time.
+
+	  Note that the APM support is almost completely disabled for
+	  machines with more than one CPU.
+
+	  In order to use APM, you will need supporting software. For location
+	  and more information, read <file:Documentation/power/apm-acpi.txt>
+	  and the Battery Powered Linux mini-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>.
+
+	  This driver does not spin down disk drives (see the hdparm(8)
+	  manpage ("man 8 hdparm") for that), and it doesn't turn off
+	  VESA-compliant "green" monitors.
+
+	  This driver does not support the TI 4000M TravelMate and the ACER
+	  486/DX4/75 because they don't have compliant BIOSes. Many "green"
+	  desktop machines also don't have compliant BIOSes, and this driver
+	  may cause those machines to panic during the boot phase.
+
+	  Generally, if you don't have a battery in your machine, there isn't
+	  much point in using this driver and you should say N. If you get
+	  random kernel OOPSes or reboots that don't seem to be related to
+	  anything, try disabling/enabling this option (or disabling/enabling
+	  APM in your BIOS).
+
+	  Some other things you should try when experiencing seemingly random,
+	  "weird" problems:
+
+	  1) make sure that you have enough swap space and that it is
+	  enabled.
+	  2) pass the "no-hlt" option to the kernel
+	  3) switch on floating point emulation in the kernel and pass
+	  the "no387" option to the kernel
+	  4) pass the "floppy=nodma" option to the kernel
+	  5) pass the "mem=4M" option to the kernel (thereby disabling
+	  all but the first 4 MB of RAM)
+	  6) make sure that the CPU is not over clocked.
+	  7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
+	  8) disable the cache from your BIOS settings
+	  9) install a fan for the video card or exchange video RAM
+	  10) install a better fan for the CPU
+	  11) exchange RAM chips
+	  12) exchange the motherboard.

+	  This driver will make CPU Idle calls when Linux is idle (unless this

+	  should always save battery power, but more complicated APM features
+	  will be dependent on your BIOS implementation. You may need to turn
+	  this option off if your computer hangs at boot time when using APM
+	  support, or if it beeps continuously instead of suspending. Turn
