Thank you, I finally got this answer from SuSE and the advise worked.
The only thing I'd like to see in Linux: the kernel
configuration/compilation options like they have in *BSD during initial
installtion. it would be nice to get rid of the SCSI noise now :)
I hope this could be useful for somebody else:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This IDE Controller is not supported by the standard kernels included in
SuSE PowerPC Edition 7.1.
However, you can try to upgrade to the newest kernel version. You can find
it on our ftp server under:
  ftp://ftp.suse.com/pub/suse/ppc/update/BETA/kernel/deflt

In order to acces this ide controller the following features in
the kernel configuration need to be enabled:

AEC62XX chipset support
CONFIG_BLK_DEV_AEC62XX
   This driver adds up to 4 more EIDE devices sharing a single
   interrupt. This add-on card is a bootable PCI UDMA controller. In
   order to get this card to initialize correctly in some cases, you
   should say Y here, and preferably also to "Use DMA by default when
   available".

   The ATP850U/UF is an UltraDMA 33 chipset base.
   The ATP860 is an UltraDMA 66 chipset base.
   The ATP860M(acintosh) version is an UltraDMA 66 chipset base.

   Please read the comments at the top of drivers/ide/aec62xx.c
   If you say Y here, then say Y to "Use DMA by default when available" as
   well.

AEC62XX Tuning support
CONFIG_AEC62XX_TUNING
   Please read the comments at the top of drivers/ide/aec62xx.c
   If unsure, say N.

You can check this after booting with the new kernel in the file:
  /proc/config.gz

If they are not enabled, you need to enable them in the kernel
configuration after doing a make cloneconfig and to recompile the kernel.

Please note, that there is no free support for self-compiling a kernel. If
you have problems with that you may consider using our business software
support services.
You will find more information about that under:
  http://www.suse.com/us/solutions/bizsupp/index.html

Best regards

         Your SuSE Support-Team
