O.k., sorry for the long delay, I've been doing some torture tests after
installing DragonFly on a NetFinity 6000R. I haven't tested it on an SMP
machine since there's no SMP-enabled IBM servers available to install
DragonFly and test it.
I have installed DragonFly on an IDE harddrive with ips compiled in the
kernel, booted from it and did a dump/restore onto the RAID partition.
The ips driver is now running as a module, so I'm sure you can use it
that way.
Oh, if you're going to install DragonFly by installworld/installkernel,
don't forget to populate your /dev on the RAID drive; I have wasted a
few hours figuring out what was wrong when it stuck in the middle of the
boot screen after having used to devfs too much :)

Anyway, the patch is here:
  http://les.ath.cx/DragonFly/ips.diff.gz

I've changed indentation and spacing to make it look similar to what is
described in style(9).

How to apply:
# zcat /path/to/ips.diff.gz | patch -p0 -d /usr/src

How to enable ServeRAID support:
  Either add `device ips' to your kernel config, or build it as module
  and add `ips_load="YES"' to your /boot/loader.conf file.

Have fun.
