The latest released BIOS is K5CN40WW, I'm using K5CN40WWT66 which is a 
later beta that partially mitigates a Windows BSOD issue. I've opened a 
Bugzilla report with the dmidecode here: 
https://bugzilla.kernel.org/show_bug.cgi?id=217718

For the acpidump I'm not sure what parts could be sensitive so I will 
e-mail it directly to you.
