I tried it on the following systems:

QEMU (640x480 32-bit framebuffer): works fine. This is the good news.

Powerbook G4 (1280x854 8-bit): first screen and a half of kernel output
displays OK, although the cursor is bright cyan instead of light gray.
The system then freezes completely.

G5 iMac (1680x1050 8-bit): Screen turns black. Letters visible
periodically underneath the cyan cursor. System eventually freezes
completely.

All three systems work fine with the old ofwfb (though the very slow
scrolling makes booting take twice as long as with syscons) and I'm a
bit at a loss to debug this correctly. Any ideas?
