$ lspci -nn
00:00.0 Host bridge [0600]: ATI Technologies Inc RD580 [CrossFire Xpress 3200] 
Chipset Host Bridge [1002:5952]
00:02.0 PCI bridge [0604]: ATI Technologies Inc RS480 PCI-X Root Port 
00:05.0 PCI bridge [0604]: ATI Technologies Inc RS480 PCI Bridge [1002:5a37]
00:12.0 SATA controller [0106]: ATI Technologies Inc SB600 Non-Raid-5 SATA
