lspci is likely wrong in this case. I've noticed that when trying to
clean up that pci id list, the same pci id is used for two different
devices (i.e. 4c66/4c6e) :-(. And in contrast to some phantom devices,
both actually seem to exist. Only the subsystem id is different I
believe between the firemv 2400 pci and some radeon 9000 mobility M9. A
bit strange that two different chips would show up with the same id,
unless that M9 is wrong and it's actually a M9+ (catalyst driver,
neither normal nor mobility, does not support this chip so I don't know
how it treats it), or the catalyst .inf file could be wrong too. This
actually is a problem, while the chips are very similar they are treated
slightly different in both ddx and dri, and both those components
differentiate only by pci id.
Ah, shows up with 4 ids then.
