Preparation: I installed rEFIt 0.13 on MacOS X. After a reboot, you should get a boot manager, which I actually didn't get.
Opening a terminal and casting the commands (from rEFIt documentation:
# cd /efi/refit
the bootmanager started and let me choose what and where from to boot.
Side note: ouf of curiousity, I deinstalled and reinstalled rEFIt using only the installer and with the third (!) reboot the bootmanager came up miracuosly - without the need to do the steps above.
After that I simply did the normal installation routine of openSuSE 11.1 - ensure, that the bootmanager is NOT installed into the Master Boot Record (MBR) but rather in the partition where your openSuSE installation resides.
Having started the freshly installed system, I recognized the following problems:
- the mouse pad cannot be tapped for clicking, you need to press down the pad
- the mouse pad does not respond to multi-finger actions which is a real problem, because you are not able to access the "right click" - there should be fixes around in the world wide web
- wireless is not working at all
- you cannot adjust the brightness of the monitor, which can be very annoying in dark ambience since the LED backlight is very bright
