There are a number of quirks that were necessary for some users but not others on the same hardware. Additionally, the combination of vendors or even driver versions/behaviors were problematic. E.g., with UMS, the drivers didn't use much gart since there was just a single static allocation. Once we switched to KMS, lots of new bugs surfaced. Chipset A plus GPU vendor B worked fined, but chipset A with GPU vendor C was problematic.
