Yep, we've still got a bunch of those running in the field, too, and many older besides. We still build new boxes using CentOS 3, also for legacy compatibility reasons.
can a 64-bit system KVM-host a 32-bit OS to handle just that board and its application?
It's something we could try on the next server, but I don't hold much hope that it would actually work.
I know KVM has the VirtIO feature for paravirtualizing a block or network device into the guest space, but that doesn't help here. The /dev nodes for this device are character devices.
Additionally, this device doesn't fit into any of the standard categories; it isn't a network card, it isn't a disk controller, it isn't a VGA card, etc. VM systems tend to cope poorly with hardware that doesn't fit predefined categories.
