I don't know. Comments from freebsd-core team? Differences using the BSD make?

Ok, how? 8)

Please, do it! Just few questions:
1) do we really need the toolchain? I have downloaded gcc2.8 and I found this
in the Install file
Configurations Supported by GNU CC
==================================
Here are the possible CPU types:
1750a, a29k, alpha, arm, cN, clipper, dsp16xx, elxsi, h8300,
hppa1.0, hppa1.1, i370, i386, i486, i586, i860, i960, m32r,
m68000, m68k, m88k, mips, mipsel, mips64, mips64el, ns32k,
powerpc, powerpcle, pyramid, romp, rs6000, sh, sparc, sparclite,
sparc64, vax, we32k.
Note: sparc64!
So does we need the toolchain? What is exactly the toolchain?
2) Can we use the gcc2.8?
3) Differences between gcc2.8 and toolchain?
4) Crosscompiling from i386 platforms: I have read the cross-compiling section
from the same document, and it does not seem a good idea 8(
This means I need an AXi motherboard! 8((
5) Have you done experiments with the booting part?
6) Can you put everything on-line somewhere? (documents, the toolchain, etc..)
Ciao Ciao
