Note mine is:
>> ahcisata0 at pci0 dev 18 function 0: vendor 1002 product 4380 (rev. 0x00)
>> ahcisata0: ignoring broken port multiplier support
>> ahcisata0: AHCI revision 1.10, 4 ports, 32 slots, CAP 0xf3209f83<CCCS,PMD,ISS=0x2=Gen2,SCLO,SAL,SMPS,SSNTF,SNCQ,S64A>

>> 000:18:0: ATI Technologies SB600 SATA Controller (SATA mass storage, AHCI 1.0)
