That's the apic problem. Disable apic on uniprocessors.

Yep. Snap.

Same. Except mine doesn't hang, it just doesn't re-init the display. 
Everything else is working fine though. Mine doesn't matter if it's 
close the lid, FN-F4 or echo 3 >> /proc/acpi/sleep. All does the smae thing.

FN+F5 perhaps? 2.6.5+ has a bug it seems in USB handling. 2.6.4 works 
like a charm with USB bluetooth for me.

Agreed.

Mine has the Intel chipset. The LED works, but that's about all... I 
haven't managed to get the ipw2100 drivers working with anything yet 
(ad-hoc not done yet sadly, but I can't get it work work with an AP either).
