I did something somewhat similar but I cheated from your point of
view. Using two disks this is trivial.

I installed wd0 (now sd0, thanks to dlg/ahci ;) with an amd64 snapshot
and partitioned the second drive in preparation for an i386 snapshot.
Now on the bootprompt, I can simply choose to boot hd0a:/bsd.mp or
hd1a:/bsd.mp. By fidgetting with boot.conf(8), you can make either
boot by default, or not boot anything by default (always wait for the
user to type something at the prompt).

Since the i386 and amd64 bootloaders support loading eachothers kernel
these days, this works great !

So, my suggestion for your case would be to simple add a (small/cheap)
drive per install. As long as the BIOS knows about the drive, you can
boot OpenBSD from it.

Cheers,

Paul 'WEiRD' de Weerd
