With kernel 2.6.13 (gentoo-sources or vanilla-sources), booting is not available
With the same configuration, previous kernel allowed my ibook to boot.
Patch and other information is accessible at following url.
And there is another thread in gentoo forum.
According to others, the above patch does not support ppc with a nvidia graphic
Steps to Reproduce:
1. build kernel
Please revert the patch you mentioned and try this one instead:
This one has been merged into Linus' tree, and (hopefully) fixes the original
issue it was trying to without breaking PPC stuff. If this one works, I'll
include in gentoo-sources.
Patch that you suggested works at least on my ibook.
But still, I have some problem in wake up after suspending.
Specifically, network modules seem to have a wake up problem.
Fixed in genpatches-2.6.13-2
Fixed in gentoo-sources-2.6.13-r1
