It appears that the issue is i386- (or 32-bit-) specific.

However, I did not need to revert r250551 to build successfully on amd64:

FreeBSD g1-227.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #2  rM/:1000032: Sun May 12 10:09:59 PDT 2013     root at g1-227.catwhisker.org:/usr/obj/usr/src/sys/CANARY  amd64
