it's not that cards are locked to later drivers, just drivers are released before certain cards can be.
so they weren't around to be written into the particular older drivers.
unfortunatly in the case of the 5950 and the 5700-this is a drawback. the 5200+ drivers all seem to suck...
thats kinda where I began this idea.
I was planning on getting a 5950 myself, but I just can't afford it with christmas and such so close, so I just started wondering about the drivers before the 4403 for my 5900 NU.
basically, if a driver still has the temp sensor, then it should be able to work on the FX cards.
so I started with the drivers I new worked for the 5800 series.
so far I have tried most of the 4300 series cards.
I tried to fool the 4200 series with many tricks...
switching INF's from one driver to another, manual editing, adding the 9-10 driver files from the 4201 to the 4403, and a few dozen other tricks...
but as long as the driver can't read the videocards temp sensor, then the driver doesn't stick.
so I haven't figured out how to get a driver lower then the 4303 to work on the FX cards yet...
but so far, this project has been pretty helpful :D
