Mac mini and pc keyboard

[Shilishper <debian@june31.com>]

Hi,
I recently installed sarge on my mac mini and noticed, after I compiled 
and installed a new kernel (and screwed up at that), that yaboot doesn't 
see my logitech itouch keyboard. Neither the first stage, no the second, 
no openfirmware after both of them. I had to borrow a genuine mac 
keyabord to to enter boot label for the original kernel. I am not sure 
that it is a correct place to ask, but who knows better about the mac 
boot process than yaboot developers? Is this problem something yaboot 
related or it is a common mac problem? But how then did macos let me 
boot from cd to install linux? I pressed 'c' key on the pc keyboard and 
it was understood.  I just need to know if i have to buy a mac keyboard, 
since it is not the last time i screwed up, and overall, it is 
inconvinient to edit yaboot.conf every time i need to boot a different 
kernel.
Thanks
