OpenBSD 3.4 on HP Kayak dmesg:

pcibios0 at bios0: rev. 2.1 0xf0000/0x10000
pcibios0: PCI IRQ Routing Table rev. 1.0 0xf4560/176 (9 entries)
pcibios0: PCI Interrupt Router at 000:31:0 ("Intel 82801AA LPC" rev 0x00)
pcibios0: PCI bus #4 is the last bus
WARNING: can't reserve area for BIOS PROM.

can someone tell me what this warning means and what should be done
about it?

also can someone help me understand what is happening below?
This does not alsways happen, but I've noticed it 2 or 3 times during
the last 10 or so boots:
