    I understand the problem there. Since this server is not technically
    work-related, it usually gets put on the far-back burner, for various
    periods of time. :(

    The last recommendation I noticed was to try and create a custom ramdisk
    to force it to load the raid1 module.

    *chuckle* Difficult is an understatement. ;) Makes me really wish I
    could host it from home... ;)

    I'm probably still looking at this the wrong way, but previous kernel
    upgrade(s) work just fine. For example, the software needed 2.4.9
    initially, but RH7.2 came with 2.4.7. I upgraded the kernel rpms the
    same way I've tried now, and it worked. What could have changed between
    2.4.9 and 2.4.20 in this respect? :|

    I've recreated the situation on a VMware virtual machine I set up. The
    only difference is that I have no control over the type of hard-drives
    are "emulated", per se, as it only allows SCSI. The real machine has
    IDE drives. Same problem. Upgrade from 2.4.7 -> 2.4.9, just fine.
    Upgrade to 2.4.9 -> 2.4.20, no RAID.

    Argh. :\ I really wish I had hardware RAID support... bleh.
