Create a system power notification callback which refreshes your GL
view contents. That's how I do it. My textures weren't being
corrupted, but the FRONT and/or AUX0 buffer's contents are randomly
hosed. I only noticed it when a realtime view wasn't running, on
waking from sleep; RV-250 (9000).
I should have mentioned that this is already a realtime view, at
about 4Hz. It does appear that selected textures are not getting
restored, as the objects they are used on are otherwise being drawn
correctly.

Just a note: we just tracked down and fixed an ATI issue that would cause
buffers to fail to be paged on after a sleep/wake in some cases. The fix is
in Tiger, but it sounds like Shaun's workaround is the best approach for
pre-Tiger.
This is good to hear (and I've had reports from my ATI users of
similar issues; they'll be glad to know a fix is coming), but the G5
iMac uses an Nvidia GPU. Is the bug you fixed ATI-specific, or did
it address something that might help the Nvidia hardware as well?
Thanks!
