Damon,

I use LVM on top of SW RAID all the time.  It a very easy setup.  Here are
two "howto" docs I use all the time:

http://www.gentoo.org/doc/en/gentoo-x86-tipsntricks.xml (the software RAID
section)

http://www.gentoo.org/doc/en/lvm2.xml

Gentoo configuration of RAID and LVM2 maps 1:1 with all other Linux
distros.

I'm currently running LVM2 on top of SW RAID 5 on 2 machines -- soon to be
4.  Performance is excellent... for the cost.

- Sebastian
