Hi. I just had to "bake" my 7950GTX (in Inspiron 9400) for the second time last night, - successful. I reinstalled the driver for it, and 179.48 is the last from Nvidia for that card.
However, I have run Laptopvideo2go drivers with modified INF files successfully in the past (196.34, 259.47, 268.27, 270.80, 275.27) when I was playing Battlefield: Bad Company 2 on this machine. Best was probably the last 3.
As qhn points out, most driver updates seem to rotate around games, and these are DX9c/XP cards at the end of the day.
For your info, - if you ever want to upgrade from the 7950GTX, go to the FX1600M (or the FX3600M - both from the Precision M6300 and Vista/DX10 ).
While both are seen as "unknown video adapter" by the BIOS, the FX1600M is a straight plug and play with full functionality (same 3DMark06 scores as the 7950gtx, but DX10).
I have the FX3600M (similar to 8800M GTS) in my M1710 but this upgrade is not so straight forward (see Englund 33's last post, on "The Big Question... thread on this forum). Plays Battlefield 3 (3DMark06 of 8000+).
Most drivers updates are mostly for games, in my opinion, and games rely on many things. If it doesn't break, don't fix it
