mounting a 4.x drive under 5.2-BETA

So I have a second drive in my 5.2-BETA running Netra X1 that I had in a
4-STABLE i386 box that I mounted as:

  /dev/ad2c            /data           ufs     rw              0       3

I get a complaint when I tried to mount it. Since mount doesn't have any
special options for mounting a UFS1 partition, I can't figure out what I might
be doing wrong...

Am I trying something that is impossible?
