Well, wsfb /should/ work no matter what, there are some Apple  
graphics chips that XF86 or Xorg don't support.

Gah, I should have guessed. I distinctly remember fixing that on ofb  
but apparently I forgot to commit :/

Hmm, all it does is to use 24bit colour and point the Xserver at /dev/ 
ttyE0 for mapping the graphics chip which it should be doing anyway,  
I don't know why his one works and yours doesn't.

have fun
