You could also consider having a separate 2GB boot partition on each
disk, without glueing them together into a RAID0. In normal use,
you'd keep them all identical, using rsync or dump|load or something,
but you would also have the ability to test upgrades by installing on
only one of the multiple boot partitions. (I do this with a two-disk
system, with a small boot partition on each disk, and a large RAID0
over "the rest" of both disks.)

I've ended up with a boot partition on each drive that holds the boot
code, the /stand directory, and a kernel.
This boots onto the original RAID5 without a problem.
The only question rattling around in my now completely addled brain is
"which kernel is running?"
My expectation is that the one from the boot partition, but my hope is
the one off the RAID.
Either way, it's all good for now. I need to get this server back
on-line so I can get back to my next insurmountable problem:
The Kevorkian Server.
