I'm fairly sure there is some magic you can apply in the Open Firmware
on the Mac Mini G4 to make it boot and install from a USB key.
Unfortunately, I don't have the time to try it out on my own Mini
right now, but I've done it successfully on a G4 tower that was
obsolete before the Mini was even a gleam in an Apple designer's eye.
I'm CC-ing this to the debian-powerpc list incase somebody there
remembers the magic.
In any case, the reason it's asking for /dev/sda1 [*] is that the
bootable CDs have no apple partition map, they are all one big
So try this:
Take a USB key you don't need and dd the businesscard or netinst iso
dd if=debian-6.0.5-powerpc-businesscard.iso of=/dev/sdx
where /dev/sdx is the device for the flash drive. Be careful! If you
get this wrong, you could wipe your hard disk.
Businesscard is just an example. Other installer iso's will work just
as well, of course.
Do your yaboot magic to boot off the hard disk. When the installer
comes to searching for the CD it *should* find the USB key and use it
for the remainder of the installation.
If that doesn't work, maybe by then somebody on the list will have
remembered the Open Firmware magic for booting directly off the USB key.
Hope this helps!
[*] On a hard disk, /dev/sda1 *is* the Apple partition map -- Apple
reserves a slot in the map for the map itself -- it's always partition
