72c2f499ce Add a fix for the VIA82C686B data corruption bug. 
This fixed the problem on the 3 platforms I've been able to test on.

I'm still of the oppinion that the BIOS should take care of this,
however some board makers only apply this when they spot a
SBLive! soundcard, but the problem exists even without a SBLive!.

This fix should probably go somewhere else, but for now I'll
keep it here since we havn't got a central place to put
such things.
