FC2: How to mount BSD partition?

[KokHow Teh]

Hi;
      I have made sure that I compile FC2 with BSD partition and
file-system support. However, I have not had any luck mounting a BSD
(OpenBSD) partition with `mount -t ufs -o ufstype=44bsd /dev/hdb4 /mnt/tmp`
command. I am dual booting FC2 and OpenBSD. Any advice and insight is
appreciated.
