I added it as follows. And, it enabled the start with the vga console. 
# Because CVS became a connection timeout, I was not able to obtain diff. 

prep/pci/pci_machdep.c::prep_pci_conf_hook() ---

                /* now look for bus quirks */
 
                if ((PCI_VENDOR(id) == PCI_VENDOR_DEC &&
                    PCI_PRODUCT(id) == PCI_PRODUCT_DEC_21154) ||
                    (PCI_VENDOR(id) == PCI_VENDOR_HINT &&
                    PCI_PRODUCT(id) == PCI_PRODUCT_HINT_HB1)) {
                        bmax = prop_number_create_integer(8); 
                        KASSERT(bmax != NULL);

However, I saw a stranger message.  This correction disabled MEM/IO of
ppb.

However, I saw IO/MEM of ppb enable in yesterday's log.

Should I compulsorily make MEM/IO of this ppb enable?
