Oh this guy has, although it crashes

elsewhere it seems that version 2-2.2 kernels needed recompiling for UFS
support.

This may be helpful

It assumes you have the support.

Unfortunately in my linux here (Mint 17) there is no sign of any UFS
modules on the machine or packages like that in the repository, which
suggests that debian dropped the whole thing upstream

In short, its one of those things that an enthusiast got sorta half
working and then gave up on, and its no longer supported.

Th recieved wisdom is to set up a small machine with BSD and mount the
drive in that, and use NFS to access it from the pi :-)
