I'll second that. When mine hang it's because I have a bug in
whatever diff I'm working on...

So start eliminating differences. Does it hang over night if you
never login? If not, then it's something you're running that does it.
So login and logout and see whether it's some daemon started by your
.xsession (dbus? that gkrellm thing that caused a 1+ load?) that
causes it. If it does hang even if you don't login, then start
checking off the system daemons. What if X is never started? Heck,
boot to single user and leave it there over night.
You were seeing ACPI taking more and more memory before; is that still
happening? Is there a correlation between that and the hangs?
Make a hypothesis ("it's caused by something in my .xsession"), come
up with a way to test it ("see if it happens if I don't login") then
do so. You have a problem; do SCIENCE on it.

Does the hang in sync happen if you're not running any processes as
you? Only happens if certain filesystems are mounted? What are the
prerequisites on it hanging?
Since this doesn't seem to affect developers, you're going to have to
do the science.
