 figure it out from the lspci -v command, and then fool the

 entering an address that is, perhaps, 0x400 lower than the

 config register group, so that it uses the 3rd register of
 that group.
 (That is 0x02 above the beginning of the group.)

The ideal fix is editing the BIOS to fix the not setting the port properly bug. 
;-) There's a BIOS hacking and editing community that most likely contains at 
least one person with the know how to do that.
