APM suspend lost! (mypost: 4octrl3)


I don't know what caused it, but my laptop won't come out of APM suspend.

The laptop is a Dell Lattitude C640, running Etch, with the 2.6.12 kernel. The 
grub menu tells the kernel to not use ACPI (it doesn't work with bios), and 
apm --suspend works fine. But when I open the lid/press the button, it comes 
to life (noise, lights, back light of screen) but the screen is completely 
blank and everything just stays like that. There's no disk activity, so 
either it's died or it's waiting on something.

This had been working fine for years, and suddenly it's stopped. Major 
inconvenience what with linux taking about 3 hours to boot up as well!

Has anyone else noticed this, or could anyone give me pointers toward 
debugging the problem?

many thanks,
