Description:

The Partition table of a Intel MAcbook is a Global Partition Table (GPT), and
not the kind usually found on x86 hardware. Additionally to the GPT the MAcbook
keeps some kind of fake MBR that contains the 4 first Partitions in the GPT to
give non OSX operatoin systems a way to boot with bootloaders. 

Unfortunatly this fake partitiontable has to be synced with the GPT after the
GPT is changed which is done automatically with OSX tools, but not at all with
linux tools that access the GPT like parted. So, if you resize the osx
partition with OSX tools and then create partitions in that free space using
the YaST2 installer, the partitions only get created in the GPT, but the fake
MBR which is later used by grub is not synced with the modified GPT.

This leads to a failing grub install at the end of Stage1 of the Installer. One
then has first to start a OSX tool (i used refit) to resync the fake mbr with
the GPT, reboot into the rescue system and then can install the grub on the
root partition. 

Howto Repeat:

o install SL10.2 on a Intel Macbook
o see the grub install fail
