Brain transplant successful.  I did map out the SATA ports on the boards 
and once I got the replacement up and running, 'raidctl -G raid0' produced
a config file with a DISKS section in the same order as my original
"raid0.conf".  Just need to tweak the custom kernel to add the siisata(4)
driver back in.

The old board had one bulging and one crusty capacitor.  While it should
be a simple fix, the replacement board is actually quite an upgrade.
The old board was a 1.8GHz Celeron w/4GB (less that used for intel
integrated video) otherwise chosen because its audio hardware and onboard
ethernet were broken.

The new(ish) board is still only 1.8GHz but has 2 cores and has 8GB
(again, less that used for intel integrated video).

I still need to replace everything and have a proper server-class machine
in the works--just need disks.

Thanks for the help.
