Got a link to the KB article? Makes me wonder if that's related to not having PAE since XP32 is most definitely supports a 4GB map:

My current system is PAE enabled, 2GB RAM w/ a 512MB video card (512MB*2 actually) and I'm not showing an RAM loss. Why would I @3GB given the 4GB limit?

No, it's a 4GB wide address space so you'd loose nothing @3GB of RAM with a 512-1024MB card.

I disagree, there is lots of articles about this including in MS Knowledge base. I have actually experienced the drop after installing a video card. In Control Panel\System\General Tab I started out with so much ram and then installed a video card with twice as much RAM and when I checked again my system ram had dropped an appropriate amount.

If you are running 32 bit OS, then a one GB card will take another 512megs of addressable memory. this means if you are currently showing 3GB of RAM with a 512meg video card, and you install a 1GB video card then you will reduce your system memory by 512megs.
