Can people please test the following patch also available at
http://www.FreeBSD.org/~jhb/patches/mlx.patch
It fixes problems when using older Mylex controllers in Alphas,
but I'd like to make sure it doesn't break mlx(4) for other
folks before committing. Mike Smith has given the patch a once
over as well. Thanks.
