bad color depth in osx

[tristan]

hi there, i got a problem with mol and my powerbook G4 17'' (nvidia)
i can run startmol -X, osx starts successfully, BUT,
display is garbaged, it seems that color depth is not correct, only 16
colors displayed.

any clue? what could cause this? is it due to my framebuffer config?
my terminal screen VT1-6 is in high resolution, but i don't know where i
could configure the color depth for console framebuffer...
on x86 machines, i append vga=791 to kernel parameters in grub, but on
ppc?

thanks for your help!!!
