David, please read his dmesg:

pcibios: BIOS version 2.10

Do you know where that comes from?

/sys/i386/pci/pci_cfgreg.c:

int
pci_cfgregopen(void)
{
        ...
        v = pcibios_get_version();
        if (v > 0)
                printf("pcibios: BIOS version %x.%02x\n", (v & 0xff00) >> 8,
                    v & 0xff);
        ...
}

I'm not stupid, ok?  The version of the PCI BIOS spec that his BIOS
implements has no relation to the vendor firmware revision of his
BIOS beyond perhaps mere coincidence.  FreeBSD has no code in it to
go figure out his firmware revision and print it to the bloody screen
claiming that it has something to do with PCI.
