Many thanks to all who have replied!
The problem was indeed one of framebuffer.

My machine is a G4 iMac with LCD.
The video card is a NVIDIA GeForce2 MX.
I had to add support for nvidia fb device in the kernel (the handbook 
states that only the OF device should be used in the case of nvidia, but 
  I obviously misunderstood this).

This solved my first problem. I got into a further one about udev, which 
  I was able to fix (support for tmpfs was missing).

And now it is a clock problem. The error message (copied by hand) reads:

Cannot access the hardware clock... try the --debug option.

hwclock --debug gives this:

hwclock: Open of /dev/rtc failed, errno=2: no such file or directory
No usable clock interface found

This is strange, as /dev/rtc exists. On the kernel side there is "yes" 
to "RTCclass", "sysfs", "proc" and "dev". The RTC to read is "rtc0".

Any suggestions?

By the way, enablecdboot did not work because I had written
"enable cdboot". My mistake.

Charles
