It compiled fine on FreeBSD 7.0-stable:
tingo at kg-work2$ uname -a
FreeBSD kg-work2.kg4.no 7.0-STABLE FreeBSD 7.0-STABLE #0: Mon Jul 21
20:40:31 CEST 2008
root at kg-work2.kg4.no:/usr/obj/usr/src/sys/GENERIC  i386

But when I tried to use, it printed two 'V''s and then seemed to be
doing nothing.

In /var/log/messages I got these:
Sep 21 12:09:35 kg-work2 kernel: umass0: CBI reset failed, TIMEOUT
Sep 21 12:09:40 kg-work2 kernel: umass0: CBI bulk-in stall clear failed, TIMEOUT
Sep 21 12:09:45 kg-work2 kernel: umass0: CBI bulk-out stall clear failed, TIMEOUT
Sep 21 12:11:55 kg-work2 kernel: umass0: CBI reset failed, TIMEOUT
Sep 21 12:13:00 kg-work2 kernel: umass0: CBI bulk-in stall clear failed, TIMEOUT
Sep 21 12:14:05 kg-work2 kernel: umass0: CBI bulk-out stall clear failed, TIMEOUT
Sep 21 12:16:15 kg-work2 kernel: umass0: CBI reset failed, TIMEOUT

The funny thing is - that situation seemed to vlock commands from executing,
or the terminals from printing outrput.
I had several terminal windows up, and a ssh session from another machine. 
I could type a command, but nothing would happen after I pressed enter.
Switching workspaces in X and switching vty's  worked fine.
In the end, I had to yank the floppy (which panicked the machine as expected).
The floppy I used was this one:
Sep 21 11:45:58 kg-work2 root: Unknown USB device: vendor 0x0644 product 0x0000 bus uhub1
Sep 21 11:45:59 kg-work2 kernel: umass0: <TEAC TEAC FD-05PUB, class 0/0, rev 2.00/0.00, addr 2> on uhub1
Sep 21 11:45:59 kg-work2 kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Sep 21 11:45:59 kg-work2 kernel: da0: <TEAC FD-05PUB 3000> Removable Direct Access SCSI-0 device 
Sep 21 11:45:59 kg-work2 kernel: da0: 1.000MB/s transfers

I will try ufdformat on a different machine now.
