A quick thanks to everyone on the list who offered tips & advice for making
my setup work.  I finally got everything loaded, configured, partitioned,
mirrored, and LVMed!

Problem 1: needed to use install-mbr to put an MBR on /dev/sda and /dev/sdb.
Problem 2: needed to upgrade LILO

Now I have the install-mbr MBR booting, which gets me to LILO (21.7) 
installed on /dev/md0 (/dev/sda1, /dev/sdb1).  The older version of LILO I 
was using (21.5) didn't seem to work with md devices (I recall reading about
that somewhere, too).

Running Kernel 2.4.4 w/ LVM 0.9.1b7 (had to make a minor change to lvm.c to 
get the kernel to compile):
