Nope. What may help is a bit more debugging. For example, does the
kernel actually boots if you add "video=ofonly" to the kernel command
line.

Next would be to hack kernel/printk.c to call btext_drawstring() on the
printk buffer, though you'd have to add a global variable "foo" that you
test before doing that, and only set it to 1 from pmac_setup_arch() in
arch/ppc/platforms/pmac_setup.c

Ben.
