Well, PPRO + 440FX is incompatible with a few chipsets mostly because
the 440fx is PCI 2.0 .

For instance, a friend of mine had horrible crashes with a 
diamond stealth and his 440fx when he switch to a matrox millenium the
problem went away. The matrox meteor is supposed to generate an
illegal PCI signal which kills the PCI bus on PPRO with the 440fx chipset.

Memory aperture for speeding up raw displays is now the responsibility
of the OS and not the BIOS so to get maximum display bandwith the OS
or X server needs to program the chipset to disable caching on a 
given memory display region.
