I was thinking of the same scheme, ie: the Linux kernel layout...  How
about having a few directories beneath the arch-dependent dir (like
Linux), think of this: for __ARCH__ in i386 alpha ppc; do 

  bios/arch/$__ARCH__/include/	-- includes: *.h, *.s, *.inc, ...
  bios/arch/$__ARCH__/tools/	-- arch-dependent tools/scripts/etc...
  bios/arch/$__ARCH__/boot/	-- minimal boot-up code to get processor
				   to have a stack and full linear memory.

All of this stuff should perhaps live under the boot/ directory.
