You can't blame that one on Familiar I don't think... I've wondered
if a few people have actually been experiencing backlight problems
and mixing up with fail-to-resume problems in a dark room :) There's
an acknowledged hardware issue with at least the newer Ipaq's and
backlights, and I think the fix is unfortunately a return-to-base.
It's something to do with an inverter, at which point I get lost:
things spontaneously fall apart when I pick up a screwdriver.

When I first installed Familiar/Opie the problem went away, and I was
hopeful Familiar has worked some magic: but it's slowly crept back,
just as you describe above. The reason it went away is because it
does if you use your Ipaq a lot, apparently :) I guess I should
see its return as a sign that Familiar is pretty stable, in that I'm
fiddling with my Ipaq less on the day now, hohum.

Compaq/HP acknowledge that even turning off/on and sliding the
brightness down/up will sometimes not resolve this, and yes, it's
a pain. But I had it just the same with WinCE.

Developers: a plea to create more problems please, so that I start
having to fiddle with my Ipaq a lot more again, and in so doing make
the backlight problem go away again.
