graphics card replacement

i've just downloaded and done a clean install of vista beta 2, build 5384. (well, me and it seems about another million people.) everything is good, except i have limited functionality with the graphics components. that is, there's no flip, flip 3d, aero, etc. checking the device manager, i see my display defaults to "standard vga", with a driver supplied by microsoft. there is no driver (wddm or other) available for my geforce4 go 440 card. i've tried "tricking" the computer by modding an inf file and loading an nvidia-supplied wddm driver for more robust cards. result: i was promptly smacked upside my head by vista.
that said, and i'll note i'm very much at the formative stage on this idea, i'm wondering how difficult and/or costly it would be to swap out a graphics card on a compaq presario r3240 laptop. can it even be done? the gpu, as noted, is the geforce4 go 440, the cpu is nforce3, with a 60-gig hard drive and 512 mg ram (which i'll upgrade soon enough). my bottleneck seems to be the graphics card, and i'm just weighing options. oh, and wondering just how big is the universe -- but that's a thread for another forum.

That's a question for a hardware (laptop) group, isn't it - not an OS question.

That's a question for a hardware (laptop) group, isn't it - not an OS devices compatibility question.
