The diff between 2.6.30.4 sound headers and current snapshot was
relatively small (700~ lines), snd_card_new() is removed, a lot of SoC
stuff was modified, etc. I patched those into my kernel headers and then
built the drivers but still the same issue. I'm now compiling 2.6.30.4
with ALSA and V4L drivers to see if I have that Oops with vanilla modules.
