I'm glad you got it working.  I was wondering about doing that a few
weeks ago, but never took the effort to try it. Now I wonder if I
could do the same for my network card (to avoid having to use the PCI
one). I'd have to "modprobe - r" the forcedeth driver and then
"modprobe" it after wakeup. How do you find out what libraries
something depends on. Also, any idea how you modprobe a driver from an
arbitrary path? I thought I tried that once and it wouldn't work
unless it was under /lib/modules.
