There is no Win7 or even Vista driver, so you have to convince the XP driver to work.
This is the version you mentioned:

Once it's extracted, you'll need to right-click Setup.exe to change the compatibility to XP (otherwise it won't run) and also set it to "run as administrator" for good measure.
As for once it's installing, I found this note:
"When this driver is installed, at first it won't go. There will be a message to "reinstall using recommended settings". Use that option, and the graphics on the computer should work. Keep in mind that it's a Win 2K/XP driver, and does not give you Aero support, however your screen should be readable."
