[LinuxBIOS] Handling different chipset versions: the right way?

[Corey Osgood]

I'm looking at working on via vt82c686b for tyan s2507, and I'm
wondering what the best way to handle the differences between 686a and
686b is. The only difference I can see is a single PCI ID for ACPI.
Would it be better to use some sort of runtime detection for this single
PCI ID to differentiate, or seperate the two entirely? Also, should I
use the whole name of the chipset, vt82c686b, or just shorten it to
vt686b (which is commonly used by via)? BTW, I'm putting off i815 again,
because I can't get the test rig out of its current use.
