Hmmm, that is called a Linux distribution btw :)

perhaps it _should_ exist to enable the user the override a hardcoded
"noapic" option in the image. I.e. you may build a floppy/cd with "noapic"
hardcoded in lilo.conf but it is convenient to be able to override it.
When I added "noapic" option this didn't occur to me... Or, perhaps a
better syntax is "ioapics=0" and "ioapics=1" but this gives an impression
that one can also say "ioapics=2" which is not the same as the easy
solution above.
