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

Based on the above, I reverted r250551 and re-started the "make
buildkernel" -- which succeeded:
FreeBSD g1-227.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #897
r250557M/250558:1000032: Sun May 12 06:44:01 PDT 2013
r...@g1-227.catwhisker.org:/usr/obj/usr/src/sys/CANARY i386
....
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

Thanks. It looks like it's actually an alignment problem and that compile
error is erroneous. I'm going to check in a fix by weakening the
alignment requirement to 32bit and then build locally but I will probably
race tinderbox to verify that it resolves 32bit.
