Well, I'll still be looking to increase performance in libata, even such ;)

But stability before performance :)

Thank Promise, too.  They are actively supporting my efforts on this 
driver with hardware and docs.  Promise has also provided Arjan (author

and they are making other efforts to better support open source, and be 
more friendly with the open source community.
