It seems to work even with the nvidia module loaded, but once I start X, it
stops working. I thought that perhaps the patch to the nvidia kernel module
for -test5 was broken, so I used my older 2.6 nvidia kernel module source
and replaced the call to kdev_val() with MINOR() but that still did not fix
the problem. I can cat /dev/video0 before starting X, but afterwards it
says "Device or resouce busy", even after I kill X.

I tried this set of patches and it didn't do anything for me either.

So am I pretty much on my own with this problem? Does anyone use a Bt878 card
with an nvidia card under 2.6? It's strange that it used to work just fine,
but after upgrading it stopped working. I might try downgrading later to
-test4, but it would be unfortunate to have to run an earlier kernel without
the VIA8237SATA chipset merged in =\

I read somewhere that Nvidia cards do not support the overlay extension, but
I had xawtv working just fine if I disabled Xv, and it worked even better if
I used grabdisplay.
