Try http://linas.org/linux/raid.html. You can find the latest RAID
software at ftp://ftp.kernel.org/pub/linux/daemons/raid/.

RH5.2 does include the RAID software, but most on the list were
disappointed that they used obsolete code. You probably will want to
create a kernel using the patches from the RAID ftp site. The latest
alpha patches and tools are usually quite good, though sometimes the
patches need tweaking and the documentation lags behind the code. Much of
the traffic on this list addresses these problems.

There is a ROOT-RAID HOWTO, but your approach is pretty common, I think.
I use a non-RAID root filesystem on a hard disk, with /usr and /home in
RAID5 and /var in RAID0. With only two disks, RAID4/5 isn't really an
option for you (3 device minimum).
