Re. XP drivers, then ATI/AMD certainly still support XP. Latest driver is 11.1 (year 2011, month 1) and if you're looking for older drivers, here's the list for XP 32-bit:

They don't have drivers back pre 8.10 though.

If you still suffer from the need to select default before changes takes effect, maybe you should try clicking your ATI installer (in Add/Remove programs) and let it do a repair install.
Or if you still have the original download, just run that.

If you disable PPF you'll also loose fog and other thing, but then again, it
is a fps-killer...
