| That's because /etc/acpi/prepare.sh tries to figure out which modules to
| unload by looking at /sys/class/net/*/driver and
| /sys/class/usb_host/*/driver symlinks, which are not present at all in
| 2.6.12.

Thanks for that tip.  Suspend to ram didn't work fine if my usb mouse was 
plugged in... and now it does!

I only have to use the kill switch to make the ipw2200 card reconnect (set it 
to on, wait 2-4 seconds, then back to off).
