The text may change slightly, but if anything, wouldn't it be better if 
all your stats consistently referred to the same device IDs with the 
same strings?

A vendor name may be updated in the list (company gets bought out, 
renamed, etc), but I'm fairly sure nothing ever gets *removed* from the 
list - it just grows as new devices and vendors are added over time.

The important information is the ID numbers -- the text attached to them 
will always be the same in meaning, even if the text may vary a few 
letters here or there (ie. a device ID that was a Pro/1000 NIC won't 
suddenly turn into a Realtek 8139 one day).

The non-verbose information is all you need for building a stats 
database. Your stats database can have its own database of the 
pcidevs.txt imported periodically, and link the information up at 
display time.
