Hi David,
sorry for the blackout period. I've upgraded to the latest and greatest 
this morning ( 2.6.17-1.2145_FC5 ) and noticed that the problem is still 
there.
However, the symptoms have changed a bit : When i close the lid, the 
machine goes to sleep ( bliking led etc ...), but when i open the lid, i 
hear the hard drive coming back to life and nothing more, the screen 
stays black and my only solution is to do a hard reboot.
I've tried unloading as many modules as possible and i came down to this 
shortlist, with no success :

jbd                    77236  1 ext3

looking at the logs here's what i get:
Jul  6 11:04:33 kaluha pmud[2093]: lid closed: request sleep
Jul  6 11:04:33 kaluha pmud[2093]: running /etc/power/pwrctl sleep battery
Jul  6 11:04:33 kaluha pwrctl: calling /etc/power/pwrctl-local sleep battery
Jul  6 11:04:33 kaluha pwrctl-local: sleep battery
Jul  6 11:04:33 kaluha pmud[2093]: going to sleep
Jul  6 11:08:16 kaluha syslogd 1.4.1: restart.

The last message is from the reboot, there's no sign of things happening 
when i open the lid, aside from the noise made by the hard drive coming 
back to life.
Is there anything else i can do to help pinpoint the problem ?
Thanks for your help.
PS: 2.6.16-1.2133_FC5 still works like a charm .....
