You could create a directory elsewhere and use UNIONFS to
merge it with your existing /dev.  I haven't tried this,
but I think it should work.

# mkdir /mydev
# mount -t unionfs -o below /mydev /dev
# cd /mydev
# mkdir subdirX
# ln -s /dev/deviceX subdirX/device

The "-o below" option is used so that any modifications on
/dev -- such as creating symlinks -- still happen on the
real /dev, not on /mydev.
