Are you sure they aren't PCI-EXPRESS ones?

walmart.com doe shave some typos in their item headlines, but the DO have old-school PCI graphics cards. You can get them elsewhere as well.

(OK, they're NVidia, we can't use 'em, but they're PCI)

Newegg currently has 47!! PCI graphics cards

Amazon's PCI category also lists PCI-Expres cards, but they have a variety. I won't list the antique ATI Rage cards there, but here's some Radeons, including an HD2400!
