In fact what I have is a Mach-O loader which load mach_kernel from "/".

Seems good but do you really need to check for embedded XCOFF in this
patch and are you really able to execute the boot-script ?
In Panther Install CD, BootX is:
<CHRP-BOOT>
<COMPATIBLE>
MacRISC MacRISC3 MacRISC4
</COMPATIBLE>
<DESCRIPTION>
Boot Loader for Mac OS X.
</DESCRIPTION>
<OS-BADGE-ICONS>
</OS-BADGE-ICONS>
<BOOT-SCRIPT>
...
<BOOT-SCRIPT>
load-base
begin
dup 6 " </CHRP" $= if
6 + dup 6 " -BOOT>" $= if
8 + true
else
false
then
else
1+ false
then
until
( xcoff-base )
load-size over load-base - -
( xcoff-base xcoff-size )
load-base swap move
init-program go
</BOOT-SCRIPT>
</CHRP-BOOT>
[...XCOFF HERE]
