It's there.

In fact, it does; from the console and from X both. Kudos, sir - I'm
impressed (and just tickled pink, too!) The two "unfixable" bugs of this
laptop from the very beginning have been its audio (which refuses to
initialize on occasion, and requires *removing the battery* plus a cold
boot to cure!) and its inability to suspend; within a couple of days,
your work and the advice of others here appear to have fixed the latter.
Thank you very much.

Doesn't appear to happen here, even after several cycles. On suspend,
the GUI flips to a message console that scrolls several USB-related
lines and shuts off (about 1.5 seconds total.) On resume, there's a
'switch to graphical mode' blink, a flash of that message console, a
very short "low-res" flash of the X screen, and it comes back to the
normal display (2-2.5 seconds total.)

That's what I've been using, although I've tried 's2ram -f' at least
twice (it appears to work just fine.)
