It looks like your BIOS doesn't support the memory stick. AFAIK OBSD
/boot uses the BIOS INT13 stuff to access disks, so no BIOS support for
the disk means you won't be able to boot OpenBSD from it.

At this stage the kernel drivers aren't important, because the kernel
hasn't even been loaded yet.

It is a bit weird that your BIOS boots from the device but doesn't
provide any INT13 support for it. But I suppose booting is just loading
one sector (the MBR) and jumping into it whereas providing support for
loading arbitrary sectors might be more difficult.
