I have a AOpen KT33 motherboard with a VT82C686 chipset, and I have the
same problems with both Linux and BeOS. It works fine with the Windows
drivers. 

I tried a couple of different versions of the via82cxxx driver, and the
moment it broke was when support for fixed-rate chipsets was added. This
seems to indicate that the bug is actually on the AOpen motherboard.

My solution was to simply to copy the last working driver version over the
one currently shipped in the Linux kernel. I'm sure this is quite unwise,
but what the heck, it works :)
