My iBook1 did not work with recent kernels (2.6.15+), 2.6.13 was always ok.
Today I did some more testing, with 2.6.16-rc4-git3.
If I boot with 'quiet panic=1 root=/dev/blah', it will hang in 75% of the boots 
before displaying the penguin.
Adding video=atyfb:off did fix it, tried it a few times. Then I removed
the quiet and video= option, and it did boot again. Then I reverted the
atyfb to 2.6.15 status and did a reboot loop.
Unfortunately, after 13 reboots with just 'panic=1 root=/x' it was stuck, after 
time_init: processor frequency = 300MHz.

"panic=1 root=/dev/blah video=atyfb:off" works better, 27 reboots and
still going.
