It would need to happen outside of HAL - at which point it becomes
completely moot to even distribute pci.ids.gz in the first place.
Frankly, I don't see any point in pci.ids.gz whatsoever - and HAL will
continue to require an uncompressed pci.ids file until someone explains
the benefit of pci.ids.gz. IOW, punt it to the distros...
