Emmanuel> Ole, do you mind having your code wrapped up this way ?

Not the least! Thank you very much for picking it up! - it has become
clear that I wouldn't ever have the capacity of bringing it beyond the
"works for me" stage:-)

And I'm even more curious about why it doesn't work on some machines...

On the P2120, this rarely happens, and I think only if the machine was
under heavy load when suspended. I'm guessing it is a missing
interrupt. Linux reenables interrupts early, and some of the drivers'
resume code could depend on getting at least one event to complete.

On the P2120, resuming from the hires framebuffer console works, I
haven't even tested the 80x25:-)
