Well, I think that to make a simple "rawrite" utility for MacOS
is enough, though I'm not using MacOS usually...

BTW, I've just made an xcoff boot-loader with netbsd.gz kernel
in a section. This boot-loader is based on bebox/stand/* code
and Dan Jacobowitz' work.
http://www.ceres.dti.ne.jp/~tsutsui/netbsd/netbsd.xcf

Put it into a hfs floppy (I'm using hfsutils on i386 :-),
type `setenv load-base 400000' and then `boot fd:netbsd.xcf'
on OFW prompt. (My machine is UMAX Apus2000 with OFW 2.0)

But I think it is better that a kernel can read itself on the booted
filesystem, rather than "a kernel in a program section".
