Windows 7: AGP GRAPHICS CARD PROBLEMS... help please

Ok. im no noob. i build computers on the side and know a fair bit about them. i have tones of nice boards like 2,8 intels or better that use agp graphics. i try to put one of the 20 agp card i have lying around in (nice cards)... geforce 128 and 256's and windows 7 dose not recognize any of them ... same computer i load xp on another hd and i dont have any problem with the cards.
i go to device manager and they always say they are standard vga cards...
is agp just not compatible with win 7 is there a hack.
what the ^(*&% im about to pull my hair out cause win 7 is all my customers want and nobody has any money to build a 500+ dollar system so i have to build all these cheap systems.
please help

Sapphire 2600Pro 512Mb AGP not Aero Compatible?

Apparently you need AGP specific drivers for your motherboard for Windows 7, and as most motherboards stopped supporting AGP five years ago, you're kinda out of luck.
