I've a crash extension called 'pci', its a direct replacement for the 'dev' command but contains its own (huge) internal database of pci information. I thought I'd finished integrating oui.txt from ieee and pci.ids from sourceforge but looking at the code today, I have *not* done that yet.... hmmm thought I'd finished that stuff. But, its on the todo list. I wrote it about a year ago and haven't really done anything with the sources since then.
It only uses the pci information from www.pcidatabase.com at present. I'll see if I can get this up on the net for use if there is interest. There are two parts, you download the source pci id information from the web and run a pre-processor on it, and then compile the extension with the header file you've created.
The ext-pci.so is currently ~1.1MB in size. Another todo list item was to shrink the size of the database via restructuring it but I don't expect more than a 25%-33% reduction in size at most.

Thanks for the reply Dave.
Even I feel it is better to change the error message to what you have
suggested. That is simplest way to address the issue as well. It gives a
clearer message to the user.
I am curious to hear from Bud on the alternate scheme and progress
as well. Bud your views ?
Thanks
Sharyathi
