No, the first order of business is to try d-i again, and fill a installation
report about it. Can you please remember me your state of things, i don't seem
to have your older email handy, and lost a bit of the context of this in
pre-christmas crazyness and lot of work which pilled on me at the last minute,

If the kernel issue is fixed, and d-i is working, then everything is fine, no
? Can you provide me info on the exact model that this concerns ?

Yes, indeed, that should be possible. Remember that OS X is unix, and thus you
could compile debootstrap from source, and use that to install over target
disk. Should work fine, but you still would need a working kernel. Let me have
a look at your kernel bug report. Christoph Hellwig may also help, since he
runs a G5 box too.

Yeah, and i still have not finished my christmas shopping, and with my new
born son, it will be a hell to find time to go shopping, oh hell ...
