The patch is against 4.11-RELEASE, and is just a backport of your commit from Dec. 5th (http://lists.freebsd.org/pipermail/cvs-all/2004-December/094923.html). There haven't been any changes to amr since release, so it should apply directly to RELENG_4 as well. I left out the subsequent ioctl fixes and LSI 320-2E support. They look straightforward, but I don't have the software or hardware to test them. If you'd like them in there before committing to RELENG_4, I can take a stab at it and post a new patch.
