SuSE on Apple MacPro?

Hi, Has anybody succeeded in installing SuSE on a MacPro? I can boot from the install CD, install the system until the creation of the boot record. Grub says something like unknown volume or can not mount volume. And Lilo has a problem with the size of the Xen kernel. Once I even succeeded in installing the whole thing with Lilo. But it didn't boot at all. It didn't even find the boot record. Even if I boot from the installation CD and chose "Boot from hard- drive", it doesn't find any boot-able partition. Probably I should install the whole thing with 'elilo'. But how can I configure elilo, if I can't access the hard-drive? Any pointers would be happily welcomed! Thanks Phil
