My apologies. The lines *should* read (mem ranges overlap):

atapci0: <ATI IXP600 SATA300 controller> port
0x9000-0x9007,0x9008-0x900b,0x9010-0x9017,0x5018-0x501b,0x5020-0x502f
mem 0xd0609000-0xd06093ff irq 16 at device 18.0 on pci0
.....
pcm0: <ATI SB600 High Definition Audio Controller> mem
0xd0608000-0xd060bfff irq 16 at device 20.2 on pci0
