I have this problem on my Latitide D600. It's apparantly a bug in the  
Dell firmware; video comes back if I suspend while docked..  
otherwise, I'm toast.

I tried to work around this on NetBSD, and my app causes (IIRC) a  
memory fault. The same app works fine before a suspend/resume cycle.  
Need to investigate to see if our vm86 code survives an ACPI suspend/ 
resume, and if not, why.

Cheers,
