Well, GEOM should let you see the devices in /dev.  Note that you will need to 
add 'GEOM_MBR' to your kernel (either as an option or kldload geom_mbr.ko) so 
that GEOM will see the MBR that the label lives inside of.  That should give 
you the /dev/ad0s1a, etc. devices.  However, I'm not sure if you will be able 
to mount the filesystems due to sizeof(long) differences.  Since the 
endianness is the same you might be able to, though.
