One way around that (with XDM) is to chown /console/* to the user when chowning the device and remove execute perms on /console so that the devices would be /console/cdrom, /console/floppy, etc. :)
Then you can get, say, amd to do the tricks of mounting it.

The risk I see is does this method let users mount with setuid?
Not by the looks of things - you can also only mount on directories owned by yourself. It's enforced in the mount syscall.
temp1# sysctl -w vfs.usermount=1 vfs.usermount: 0 -> 1 temp1# suspend Suspended
mount vn0 /mnt
mount: Operation not permitted
mkdir blah
mount vn0 blah
mount | fgrep blah
vn0 on /usr/home/dwmalone/blah (ufs, local, nodev, nosuid, mounted by dwmalone,
writes: sync 2 async 0, reads: sync 14 async 0)
umount blah
fg
su temp1# sysctl -w vfs.usermount=0
