Well, some of the test systems only have IDE but no we
aren't in the "try all of the IDE chip set" support business.

I'm always open to proposals but I've only really seen requests of
"I would like to test vendor A's hardware". In my mind that is
a Vendor A problem not a generic OS or driver issue. Now after
saying that if there is a class of issues that require a configuration
I'm happy to look at providing that.

Agreed even if they are all different chip sets and controllers.

On a side note:

I am impressed with the serial ATA and the couple of products
that I've seen so far. I think that this could remove the last barrier
for ATA drives in larger systems and wait to see what products people
come up with in the near future.
