This change made into the kernel in commit 9a3b103c... Today, I tested a SIS968 board whose lspci -nn output looks like the following. 00:00.0 Host bridge [Class 0600]: Silicon Integrated Systems [SiS] 671MX [1039:0671] 00:01.0 PCI bridge [Class 0604]: Silicon Integrated Systems [SiS] PCI-to-PCI bridge [1039:0004] 00:02.0 ISA bridge [Class 0601]: Silicon Integrated Systems [SiS] SiS968 [MuTIOL Media IO] [1039:0968] (rev 01) 00:02.5 IDE interface [Class 0101]: Silicon Integrated Systems [SiS] 5513 [IDE] [1039:5513] (rev 01) 00:03.0 USB Controller [Class 0c03]: Silicon Integrated Systems [SiS] USB 1.0 Controller [1039:7001] (rev 0f) 00:03.1 USB Controller [Class 0c03]: Silicon Integrated Systems [SiS] USB 1.0 Controller [1039:7001] (rev 0f) 00:03.3 USB Controller [Class 0c03]: Silicon Integrated Systems [SiS] USB 2.0 Controller [1039:7002] 00:04.0 Ethernet controller [Class 0200]: Silicon Integrated Systems [SiS] 191 Gigabit Ethernet Adapter [1039:0191] (rev 02) 00:05.0 SATA controller [Class 0106]: Silicon Integrated Systems [SiS] AHCI IDE Controller (0106) [1039:1185] (rev 03) 00:06.0 PCI bridge [Class 0604]: Silicon Integrated Systems [SiS] PCI-to-PCI bridge [1039:000a] 00:07.0 PCI bridge [Class 0604]: Silicon Integrated Systems [SiS] PCI-to-PCI bridge [1039:000a] 00:0d.0 VGA compatible controller [Class 0300]: ATI Technologies Inc Radeon RV100 QZ [Radeon 7000/VE] [1002:515a] 00:0f.0 Audio device [Class 0403]: Silicon Integrated Systems [SiS] Azalia Audio Controller [1039:7502] 00:10.0 RAID bus controller [Class 0104]: HighPoint Technologies, Inc.

Can you please post lspci -nn output on your machine? It seems the blacklisting was too wide. Thanks. -- tejun
