Ale vase lspci pise:

00:06.0 Multimedia audio controller: nVidia Corporation: Unknown device 006a (rev a1)
00:08.0 PCI bridge: nVidia Corporation: Unknown device 006c (rev a3)
00:09.0 IDE interface: nVidia Corporation: Unknown device 0065 (rev a2)
00:1e.0 PCI bridge: nVidia Corporation: Unknown device 01e8 (rev c1)

To unknown device je vlastne u vseho. Zapomel jsem pri kompilaci na
neco?

CONFIG_PCI_NAMES=y
