I applied patch listed at http://www.peach.ne.jp/archives/rpi/patch/ along with
bcm2835_asm.S and bcm2835_asm.h files and got errors on buildkernel
using Tim's scripts:

Probably some header file ordering/missing issue? I am using head @
revision 244918.

But the good news is that I could boot up my rpi successfully using
freebsd-pi-clang-20130101.img.gz :-)

Thank you for your work,
Hiren
