Why are you using /dev/fb0? The output below tells you the ivtv
framebuffer device is on /dev/fb1. Try again and see if this gets rids
of the error. Then try the saa7127 tests.

It may also be a good idea to run in text mode (run level 3) until you
start to get the X server running on the PVR350. You may find you end
with the FB now on /dev/fb0 if your current video drivers are not
loaded in the future. If so, be sure to adjust the xorg.conf file to
reflect this.

Assuming things work, you need to make sure you specify the correct
BusID 1:8:0 and correct FB device /deb/fb1 in your xorg.conf file
after having installed the X driver.
