Anybody gotten the vn driver working here?  Following the example from 
the vnconfig(8) manpage:

basalt# vnconfig -v -e /dev/vnd0c /var/tmp/testfile swap
/dev/vnd0c: 655360 bytes on /var/tmp/testfile
swapon: Invalid argument
basalt#

I have in my kernel config file:

pseudo-device vn	4

The `mount=/mnt' feature doesn't work either...invalid argument, once again.

So, did I miss something, or is this just broken?  Oh, my kernel is 
swapgeneric, if that matters...
