I know a number of people that run their mylex cards in jbod mode and
use software raid;-)

You're thinking of it the wrong way. You just create a bunch of
partitions and make them into raid devices. You shouldn't be using the
entire disk or you will break autodetection.

Lilo deals well with raid 1 devices. I typical create a small raid 1
mirror as /boot. Just be sure to install your bootloader on to all
drives. Newer versions of lilo will do the right thing if told to use
/dev/mdwhatever.
