Description Egbert Eich 2004-11-30 00:15:41 UTC 
The OS specific PCI probing code for Linux has a heuristic to check for the
presence of /proc/bus/pci/00. This only works if bus 0 is really populated which
may not always be the case.

[FIXED_X11R68x] Fix

Attached fix probes for presence of /proc/bus/pci/<bus_num>,
using the bus number we want to probe.
Comment 2 Egbert Eich 2004-11-30 00:43:59 UTC 
Fixed in CVS head.
