	If you mount it on FreeBSD then you can do something like this
(taken from man freebsd-version).

mount -rt ufs /dev/ada0p2 /mnt
env ROOT=/mnt /mnt/bin/freebsd-version -ku

	You could inspect the sources of freebsd-version to find out how
this is done.

	The kernel version is pulled from the kernel, I'm not sure where
the userland version is stored.
