Cheers. Now to deal with the fact that i get a black screen where I
should be seeing twm, and the fact that after hitting C-M-BS I don't get
my syscons back. :( Is there no winning? :)

(Do I have to install twm too? (also the led on the monitor isn't doing
anything weird that would indicate out-of-range so i have no clue of the
bug)

Okay, i'll check that when i boot up again, I had to force power down in
a moment of lack of clarity of mind.

I don't know how display sleep works - any pointers at docs would be
appreciated. I don't like the idea of my 17" trinitron sitting there
acquiring burn-in of console text, even though it would be AWESOME.

I don't need suspend support so much - I'm fine leaving boxes running
for days, weeks, months at a time. :)

Thanks very much.
