Thanks.  I seem to get various processes eating immense amounts of time
and memory when the tablet gets into wonky states, but I haven't found
what *triggers* it yet.

The card checked out okay on windows, and the files all seem valid.  I've
reflashed, and installed even less than before (I'm putting things back
one at a time and waiting a while, to see when weirdness begins).

I haven't had one of the weird sluggish episodes (which is when I found
the various processes eating so much time) yet, but I do have the battery
running down in ways I don't understand.  Also I'll lock the screen and
put it down, and when I push power the next day get what I think is a boot
(does the progress bar go across the bottom of the Nokia logo screen for
anything except a real boot?).

So far all I've installed since the reflash (with what I remember as 51-3
of OS2008) is OpenSsh and FBREADER.  I'm in the middle of a book in
FBREADER, so that's the key application at the moment :-).

Good point, should have looked at that before.  I'll keep that in mind in
future (tablet is at home, I'm at work now).
