The reason the Soekris net6501 has hw.ncpufound=1 in bsd.rd is stupid. The net6501 has MP BIOS, but not ACPI. Only the GENERIC (thus also GENERIC.MP) and RAMDISK kernels on amd64 and i386 include mpbios(4), RAMDISK_CD doesn't.
Is there any reason we don't have mpbios(4) in RAMDISK_CD? Are there space constraints to consider? It looks like an accidental omission to me. make release on amd64 works with this and the resulting bsd.rd has hw.ncpufound=2 on the net6501. I haven't tested i386.
