Actually, I must admit, this doesn't work for me - I just tried. Upon
resume (from from disk and from RAM), the kernel emits uevents to remove
the devices, then adds them again. I don't see other device nodes being
used though - my guess is that you have open files on the drive when you
tested this? Hmm.. I can only guess that you didn't mount the partitions
through HAL (using gnome-mount or GNOME) because if you did, we would
have lazy unmounted the file system when we saw the device node going
away...

Anyway, I submit that this is a bug with the kernel... although I'm sure
some people would argue this is how it works (since bus enum and sending
out deltas is *hard*) and that it's not a bug. Anyway, I filed this bug
