Well, mine has the same chip id:

I see. When I first bought this laptop, I installed Debian and compiled a
2.6.9 kernel I was puzzled when I discovered I couldn't put it into sleep
(I had previous experience with an iBook 2.2 G3 I used to own before).
Then, inspired by the fake-sleep patch, I changed the pmac_features.c file
and I did the same test (direct ioctl() to /dev/pmu, similar to what pmud
does) and the machine became zombie: half alive, half dead X-D
Finally, where can I get those highly experimental patches to race my
creature? ;-)
Thanks in advance.
