Just to complete the pattern: ASUS S8600 gives me the following:

PCI: Found IRQ 5 for device 00:0c.1
PCI: Sharing IRQ 5 with 00:00.2
PCI: Sharing IRQ 5 with 00:06.0
__iounmap: bad address cc800cb7
__iounmap: bad address cc804b64
SBF: Simple Boot Flag extension found and enabled.
__iounmap: bad address cc807bd8
__iounmap: bad address cc802cb7
SBF: Setting boot flags 0x1
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16)
