This is used in the Hauppauge PVR-350 card. There is a driver
homepage at <http://www.ivtvdriver.org>.
+ In order to use this module, you will need to boot with PAT disabled
+ on x86 systems, using the nopat kernel parameter.
+
To compile this driver as a module, choose M here: the
module will be called ivtvfb.
