I tried to build new drivers from v4l hg for 06/08/10 and when I tried
to load drivers I got a kernel oops. Kernel is 2.6.34 64bit for amd cpu

See:
http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/20198
http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/19904
The Oops appears to be in the same place as the Oops I analyzed in the
second link. However, your compiler, like mine, decides to code the
comparison against RC_DRIVER_SCANCODE (which is 0) first:
4f: 83 3a 00 cmpl $0x0,(%rdx) <---------- Oopsing insn
Right about here:
http://linuxtv.org/hg/v4l-dvb/file/23492745405c/linux/drivers/media/IR/ir-sysfs.c#l226
As mentioned in the first link, please try the patch found here:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=84b14f181a36eea6591779156ef356f8d198bbfd

Looks like the patches fixed it. At least no oops this time. Now to
install xine/vdpau and see if it all works
