This has nothing to do with the routing issue, but is a bigger problem by
itself :(

The VIA chipset is buggy, and your Soundblaster Live! increases the likelyhood
of triggering that bug. This is a rather well documented problem, read an
english article about it on http://www.au-ja.de/review-kt133a-1-en.html and a
german article on the discussion of this on the lkml on
http://www.au-ja.de/review-kt133a-linux.html (if you don't read German this is
not a problem, as all links found there refer to english pages).

You seem to have bad luck, as the 686a should not be a buggy as the 686b.

Bottom line: Try to get a BIOS upgrade and hope that VIA will opensource and
contribute their Windows patch to linux...

Regards, Axel.
