No, but some folks have found some relief by messing around with parameters
associated with the cards installed, etc. There are some postings in the
archive from several month ago, and again this past week.

As I understand it from others (mostly from folks that mess with audio),
the pci bus implementation (eg, controller) on the motherboard is not
always very good and apparently relates to the actual chip set in use
on that motherboard. The audio folks tend to swap motherboards as 
opposed to the small incremental improvements seen in adjusting
latency settings noted above.

I've not heard of an approved motherboard for *; sure wish such a list
existed (as do many others).
