This is not this one :-) My patch changes a few things in the
assembler, not in the boot blocks.

Mach.all bombs out because it is linked as a QMAGIC binary. It seems
that the current boot blocks are not able to boot a QMAGIC kernel. I have not
looked into it: I have simply modified the mkbootimage script in Mach4 to make
it generate a ZMAGIC binary (simply add -Z to the call to ld). BTW, I noticed
that everything under FreeBSD is linked as a QMAGIC binary except the kernel
so I suspect that the boot blocks bug is already known.

Ok, I have to update them (I will work on it this evening) and I'll
send them to this list tomorrow.
