Anybody anny experience with GA-K8VT800 AMD64 motherboard and 5.1 output?

When running the speaker test program on Gigabyte GA-K8VT800, the rear 
L/R and center/LFE channels are switched. The rear L/R and center/LFE 
connectors are connected on a seperate bracket (Gigabyte Surround-Kit) 
and thus not on the mic/line in connectors. According to the surround 
test tool in Windows XP, the speakers are connected correctly.

I'm using the ALSA version included in Linux kernel 2.6.6

It uses a VIA VT8237 south bridge:

00:11.5 Multimedia audio controller: VIA Technologies, Inc. 
VT8233/A/8235/8237 AC97 Audio Controller (rev 60)

And a ALC658 AC97 codec:
