On 7.0-stable:
root at kg-i82# uname -a
FreeBSD kg-i82.kg4.no 7.0-STABLE FreeBSD 7.0-STABLE #1: Sun Mar  2
01:18:27 CET 2008     root at kg-i82.kg4.no:/usr/obj/usr/src/sys/I81K  i386

The first hunk fails, see attached file.
I have btx.S revision:
 * $FreeBSD: src/sys/boot/i386/btx/btx/btx.S,v 1.44 2006/12/06 17:45:35

Is the patch supposed to work on that one?
It fails when building:
root at kg-i82# cd /usr/src/sys/boot/i386

Any hints on how to fix it?
