Looking at GENERIC_LAPTOP, I added in the same PCIBIOS options, namely:

options         PCIBIOS                 # PCI BIOS support
options         PCIBIOSVERBOSE          # PCI BIOS verbose info
options         PCIBIOS_ADDR_FIXUP      # fixup PCI I/O addresses
options         PCIBIOS_BUS_FIXUP       # fixup PCI bus numbering
options         PCIBIOS_INTR_FIXUP      # fixup PCI interrupt routing
#options        PCIBIOS_IRQS_HINT=0x0a00 # PCI interrupts hint. IRQ 9 or 11
options         PCIBIOS_INTR_GUESS      # see pcibios(4)

make depend && make && cp netbsd /netbsd

But appears to have the same issues. Doesn't seem all the VERBOSE either? But 
strings on /netbsd confirms my options are in there:
