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.

It boots with video=atyfb:noaccel ?
I suggest you report that to the linux-fbdev mailing list. That problem
seems to happen with some wallstreet powerbooks too, there is definitely
something broken there...

Using an older DVI TiBook, atyfb has been broken at least since 2.6.8 or
so, and still is with 2.6.15, in that it can't seem to synchronize with
the LCD and maybe 50% of the (re-)boots produce just more-or-less
shimmering/flashing garbage on screen. Doesn't completely hang though...

Except that no tibook ever used atyfb...

Damn straight! I stand corrected (confused with one PC laptop), it's the
radeon thing then..
