Do you have to do a force remove, or will it unload cleanly? I have
forced module unloading turned off in my kernel, which may be the cause
of my problem...

What do you mean by a "reference"? Does it claim to be in use when you

Yeah, I get crashes on resume too... Sigh. I never thought I would, but
I actually miss APM. The lack of APM support on my laptop has been a
never-ending headache.
