Interesting...  I have a ICH4 in my Sony:

atapci0: <Intel ICH4 UDMA100 controller> port 0x1860-0x186f at device 31.1 on pci0
atapci0: Bus reserved 0x10 bytes for rid 0x20 type 4 at 0x1860
ata0: at 0x1f0 irq 14 on atapci0
ata0: [MPSAFE]
ata1: at 0x170 irq 15 on atapci0
ata1: [MPSAFE]

I'm not running the latest in the tree because I'm having a geom
crash that I'm trying to get data for phk.  I too have no com ports.
