[aliet]

Public bug reported:

Binary package hint: linux-image-2.6-686

First as all, thank's for this geat job, I'm testing Dapper with a new
Fujitsu N3210 Lifebook, everything is working ok even the winmodem, but
I'm having a problem with suspend to ram, after I enable this feature in
acpi, I suspend, the lifebook, beeps, and actually suspend, but it can
not recover from the suspend,all I get is a black screen, any ideas?,
