"MediaGX" is a brand name for the CPU side of the CPU+5510/5520/5530. The history goes something like this. Cyrix introduce MediaGX processor and chipset. Basically an embedded 486 with all the glue on a few chips. The CPU acquires MMX (GXm) the chipset goes very integrated 5520, then a bit less integrated 5530, then adds new stuff like video overlay in 5530+. Nat Semi buys that chunk of Cyrix. The processor get renamed "Geode", the chipset eventually turns into the 1200 and so on. NS then integrate the entire thing onto one BGA chip (2200 I believe) None of it was ISA, none of it works on 4.2. I assume 4.0 the probe code for PCI devices that answered to ISA probes worked differently as 4.0 found the chips but didnt work, 4.2 doesnt work at all. 3.3.x worked variably depending on the patches used (the base one was very wobbly until 3.3.6) > If your code fixes the original MediaGX then we should apply your fixes. > The geode driver only deals with 5530 (not 5520 or 5510). I'm still doing some debugging on older 5520 (problem with mode switch bugs in the older firmware). I don't have 5510 (and its very rare). > > bits I needed fully but I see no reason to keep the code I have.

Once I get time I will do - would you expect the CVS driver to backport (well more just compile) on 4.2 ? - that makes it a lot easier to test plus its something that has to get done as real Red Hat XFree86 work so easier to schedule.
