Yes, any XP driver is considered XPDM, I also had the constant driver problems with my old Intel 82525? chipset.
Try installing the driver, Then rebooting and keep tapping F8 and A menu will appear, Select "Disable Driver Signing Enforcement" (or something very similar to that) then press enter, see if that fixes the problem, if it does post back so I can tell you how to make it always disable driver signing enforcement
Cheers,
