Remembering that many ppc-specific patchtes found their way into
linux-2.6.11 I took a look at Ben's page 
<http://gate.crashing.org/~benh/>.

I used the various "albook-ibookg4-sleep*.diff" patches, built and
tested the various kernels. Testing means here: Would the ibook wake
up after putting to sleep.

Here are the results:
Kernel            Did it wake up?

2.6.9-vanilla     Yes
2.6.9-sleep       Yes
2.6.9-sleep4      Yes 
2.6.9-sleep5      Yes
2.6.9-sleep6      No
2.6.9-sleep7      No

Now I took the linux-2.6.9-sleep6 source and exchanged one file
'linux/arch/ppc/platforms/pmac_cache.S'. (I used the version out of
2.6.9-sleep5.)
My ibook comed now back to life after putting to sleep. 
Please note,  there are only small  differences of the two versions
of pmac_cache.S in  2.6.9-sleep6 and in 2.6.11. 

So, I think the cache handling is broken in some way.

HTH,
Frank
