There is a patch on the Sourceforge site for PCI Latency.  It should be
trivial to modify it for the VIA fix.  However, I think there are
further problems in the binary component of the driver that would
require reworking to solve.  You could implement a new function outside
the binary driver, and then mess around the symbol in the binary part
so the linker doesn't find it also, and get confused.
