I'm about to gain access to an S2881, which is a similar board (different
layout but same parts).

Hm, triple fault or other hardware reset. This usually indicates bad
hardware.  Have you tried swapping the RAM between the systems and seeing
if the problem follows?  An unrecoverable ECC fault can cause a reboot,
along with strangeness caused  by temperature/power supply/etc.  Or the
board could be Just Plain Bad.

Considering you have one working machine, adn this is a very popular
board, I don't think it s abasic problem with FreeBSD and this hardware.
The worst thing reported is interrupt routing usually.
