Transmeta settings

[mads.samsing at webspeed.dk]

Hey everyone.

I have just installed FreeBSD 5.3 on my laptop:
ECS iBuddie A530 with Transmeta Crusoe processor.

But I am a little confused. I have been running Gentoo Linux
for a while and found out, that I should compile with
-march=i686.

But when I boot FreeBSD it says i586-like CPU.
And it has mmx support.

Should I compile with
CPUTYPE?=i686 or i586/mmx or even i586?
