It shouldn't be that slow!
Look at your system log and/or run with -vvv to see why it's so slow.
We've a couple of speed-ups that might help (one uses sysfs to reduce
the number of devices to scan) - they're in the queue of things waiting
to be checked into CVS after the repository move.
I'll try to get them imported tomorrow.
