 Tried this unsuccessfully, but fixing cpu freq to 100Mhz (instead of
 133Mhz) seems to work...
 
 I've read something about disabling firewire in the bios, but I have it
 on a separate card (not in the MB), and I can't remove it for the moment...
 
 I'm not kernel developper, but I may try patches or ?
