Please do make an "intrusive" patch.
It is good to see patches with '$ARCH'
The current Makefile has a line with an "fix me request"
(# Create a bootable floppy image. i386 specific. FIXME)
So please don't add an other hardware dependici in the Makefile.
See http://lists.debian.org/debian-boot/2003/debian-boot-200304/msg00416.html
where I use '../scripts/mk-tftpboot-img' to do the architecture specific
stuff.

Under which name should that new-file go? (Which is "hfs.map" ?)
