Re: Anyone have data sheet for AMD 2128103C PCI SMBus controller?

Hmmm, I guess this is a "nevermind".

It seems that this device is handled by the piixpm(4) driver in OpenBSD, 
from which we imported our piixpm(4).  So I 'll just add a new entry in 
the match list for PCI_PRODUCT_AMD_HUDSON_SMB and it "should just work".

:)

I'll give it a try, and if it works I'll commit the changes.
