Now I _really_ which I had brought the laptop to work this morning;-) > You should get "ACPI: Subsystem revision yyyymmdd" and "ACPI: System [ACPI] ( > supports S0 ... S5)" Got that.

Well, it's S4 I'm trying to reach anyway, and it's there for sure. > If you have S1, you should be able to do 'sleep' (equiv of apm -s).

Perhaps S5 is useful right after <Alt><SysRq><S> <Alt><SysRq><U> ;-) Anyway, since I can suspend (to disk) and resume fine as long as I don't have X running it must be related nvidia/agpgart/<whatever>, or? Anyway, I'll try to fiddle a bit tonight, but unfortunately I'll be out of reach for mail until tomorrow:-( (Not having internet access is not a real benefit when trying to get new stuff working...)
