Tested, and Alpha5 also works fine on EFIKA.
Some hints, if one has an empty HDD and wants to install openSUSE on it. As the installer needs (a lot) more than the available 128MB of RAM, a swap partition or file is needed. The easiest to achieve it is to use an USB stick and create a swap file on it. It needs an additional boot parameter:
to load necessary kernel support. Even if the USB stick is not seen from the firmware prompt (in which case one needs to boot from TFTP), it can be used once Linux is booted. Creating the swap file takes a lot of time...
As I have yet to find an USB CD / DVD, which is recognized by OF, the easiest way of installation is through the network. Setting up apache with YaST is just a few clicks of the mouse. Loop mount the DVD somewhere, where apache can find it, or make it available where it is. Then the full boot parameter (until hw detection on EFIKA is completely solved) is:
boot inst32 insmod=pata_mpc52xx insmod=usb_storage textmode=1 install=http://server/directory/
This assumes, that DHCP available on the network. 'textmode=1' is there to save sam RAM and speed up installation by less swapping, as the text mode installer uses considerably less memory as the shiny graphical one.
