I am not! Antonino Daplas is. Adding him to the CC list, although I guess
he reads linux-fbdev-devel.

The only part I can help with is the i2c stuff, which caused trouble
already, but so far I couldn't find anything relevant. The nvidiafb
driver is quite new, and it's natural that it needs some debugging. I
suspect that the driver has some severe problem with the way it handles
resources, as was suggested by our previous (failed) attempts to debug
it. I'd be happy to help with the debugging but unfortunately (no quite
so) I don't have any nvidia device in my machines anymore.

Somewhere else in this thread, Randy suggested that some __devinit stuff
wasn't really. I think it would be worth investigating this first, and
make sure that nothing is incorrectly tagged. The oops reported by Miles
sounded like large memory chunks had been freed when they shouldn't
have. I think I understand that erroneously tagging things __init might
lead to that kind of trouble. But maybe it's a completely different
problem, I'm really only suggesting this because I don't get what's
going on either.

Thanks,
