I have just tested that patched on FreeBSD 9.1-p7 and it works
perfectly. I am able to boot the OS with no issues and mounting CDROMs
works fine as well. One thing to note is that it does change the disk
from /dev/adX to /dev/adaX which is something that was happening between
FreeBSD 9 and FreeBSD 10 anyway. Anyone who applies this patch should
update their fstab before rebooting.

Thanks again Roger and Justin -- you've just made a huge impact in
FreeBSD usability on XenServer.
