[BUG] PPC suspend to ram broken on 2.6.18.1

[Charles-Edouard Ruault <ce@ruault.com>]

Hi All,
i'm running Fedora core 5 on my Powerbook G4 laptop, i'm using the 
Fedora provided kernels and since version 2.6.17 i'm unable to have the 
laptop suspend to ram as it used to do before.
I'm unplugging the network cable, the usb mouse and the power cord. Then 
i close the lid. I don't see the blinking led
When i open the lid nothing happens, black screen. The only way out is a 
hard reboot.
Here are the last logs i see in /var/log/messages:
