I once tried it with debain (home brew kernel) on my qube and my sweet
purple box went totally bananas. However I recall somewhere in my memory
that the gentoo-port for qube had 64bit support and it was supposed to
work (can be mistaking though), didn't try it since the install was to
complicated / time consuming for what I use my qube for.

For this part (I'll just presume netbsd still works mainly like linux ;)
*flame flame :P*) isn't hotplug needed ? So it will recognize your
usb-hardware ?

I thought they had to mislead the bootloader so it thinks it's still
loading the original kernel ? (Can someone correct me / fill in on it ?)
