  try lspci, here's output on my system:

jojda:/etc/X11/fvwm# lspci
00:00.0 Host bridge: VIA Technologies, Inc. VT82C693A/694x [Apollo
PRO133x] (rev c4)
00:01.0 PCI bridge: VIA Technologies, Inc. VT82C598/694x [Apollo

00:0f.0 VGA compatible controller: 3Dfx Interactive, Inc. Voodoo 3 (rev

jojda:/etc/X11/fvwm# 

  so I guess on my system it would be voodoo card, I guess those number
at the beginning of the line refer to the same 'something' that your
number refers to...
