Here's how I'd do it:

Set up a new disk (this does require that you can get a new chunk of  
DASD; under z/VM, of course, this is usually really easy.  LPAR, not  
so much.)
Mount it from the SuSE system.
Bind-mount /sys, /proc, /dev
debootstrap into the new disk
run mkinitrd/zipl on the new disk

Then shutdown the SuSE system and IPL from the new device.
