It may be too late to jump in, but anyway; I happen to be trying to port
it (initially I was trying to port it to -STABLE last year).
It boots from IDE drive and detects the controller properly, but needs
some more tweaking to make it work. Currently I'm working on converting
bio and geom changes back into 4.x style. I'm on holiday and I don't
have console access, so don't expect me to come up with it in a few days.
On the other hand, if you already have working ips driver, please let me
know, I'm willing to test it.

By the way, one thing I'm worrying about is its stability; I'm still
able to reliably panic it on FreeBSD-CURRENT. If you search the archive
for the subject `lots of "exclusive sleep mutex"', you'll find the detail.
