  Thanks, I'll commit the change.

  One thing to try is the simplistic OpenFirmware frame-buffer
console that I've done for powerpc (powerpc/ofw/ofw_syscons.c).
As long as there is a linear frame-buffer that can be mapped it
should work OK. This may not be the case for something fancy like
Creator, but could work on others.

later,

Peter.
