You don't need OFB_FAKE_VGA_FB for wsfb - that's only needed for 
drivers that insist on trying to mmap() the ISA VGA framebuffer.

So XFree86 could mmap the IO range.

This looks ok.

This is odd. There was no change in ofb's mmap method lately - I'll see 
if I can reproduce this.
Did you get any additional kernel output?

Meanwhile please try this instead:
- - remove all references to ofb from your kernel config
- - add this:
genfb* at pci?
wsdisplay* at genfb?
and see if X does any better. Genfb is a more generic framebuffer 
driver, it doesn't contain anything macppc-specific and works for 
instance on sparc too. It doesn't know about enabling cacheing for the 
framebuffer though.

have fun
