Reproduces on my QDI Titanium IB, 430TX chipset, 64MB SDRAM K6-200.
These are the files in /proc/bus/pci/00
-rw-r--r-- 1 root root 256 Mar 4 22:19 00.0 -rw-r--r-- 1 root root 256 Mar 4 22:19 07.0 -rw-r--r-- 1 root root 256 Mar 4 22:19 07.1 -rw-r--r-- 1 root root 256 Mar 4 22:19 07.2 -rw-r--r-- 1 root root 256 Mar 4 22:19 07.3 -rw-r--r-- 1 root root 256 Mar 4 22:19 0a.0 -rw-r--r-- 1 root root 256 Mar 4 22:19 0b.0
And 07.3 is the culprit. All others do not cause any problem.
