Probably good intentions, not very much more...

I was able to implement something like that (called it 'reprobe') just
opening /dev/rsd0c, and issuing the respective ioctl on it (in theory,
it should not be necessary to open any scsi device to tell it to 
reprobe, because there MIGHT not be any up yet, but that looks like a
chicken&egg problem..).

If you count CD-roms in on that, sure. To allow removal, just 'umount' the
filesystem, eject it, replace with new media, and 'mount' again.
