Sounds like the very bug I'm chasing. It chokes on the FBIOPUT_VSCREENINFO
ioctl. The mode in question is reported as:

xfree init mode:        64902   1024 1064 1200 1344   768 771 777 806
fbdev init mode:        15407   1024 40 136 144   768 3 6 29   16 0:0:0

with the only thing that seems fishy the 0:0:0 as the res:blue:green
length values.

I'm going to disable the ioctl and see where it barfs after that.
