SLES10 PPC Beta 6 and all the previous betas

(I understand Beta 6 isn't quite fully ready but I wanted to see if Beta 6 PPC will boot on my newest G5 Mac which it did. Beta 6 looks like the best beta so far that Gnome and KDE desktops actually run properly.)

In all previous betas including Beta 6, during installation, Boot loader will always fail to install. The feedback I got were SLES10 PPC isn't officially supported on the G5 Mac. But when I used Yast, System, Boot Loader configuration, it showed something interesting that suggested SLES10 PPC boot loader is designed to run on a PPC Mac:
In the Boot Loader Settings screen, go to Boot Loader Installation tab. It showed:
Type
Boot Loader
PPC

Boot Loader Location
HFS Boot Partition - no valid boot partition

HFS exists only on Mac. So, if SLES10 PPC doesn't support PPC Mac, then why does the Boot Loader showing it's looking HFS partition?

Anyway,
I tried creating using Partitioner a HFS partition, but Boot Loader still couldn't see it.
I also tried putting in a second SATA hard drive that was installed with Mac OS X.4 which has HFS partition, but Boot Loader still can't see it.

What I think is if Boot Loader was designed to run on PPC Mac HFS partition, but the code is broken in SLES10. I don't know if SLES9 PPC Boot Loader works on the PPC Mac. Never installed it.
