dmesg kernel 2.6.37-rc6 video output corrupted in BIOS emulation


This is dmesg I made from last available kernel, this is a vanilla kernel (no
patch added) running on MacBookAir 3,1 in BIOS emulation. The screen is not
blank, I will try to decribe it :
 - on the left the screen is good over about 200 mm from left to right, then
there is garbage till 2/3 of screen, then blank. The garbage are readable
characters, but ugly.

It's lock like that hsync is wrong.

I didn't start X at all, I waiting for working console.

do mmiotrace is needed ?

Best regards.
