Description of problem:
PowerMac G5 DP 2.0 Early 2005, iirc 1GB RAM, switches to text mode due to not having 1280MB RAM
(despite having 9GB of swap). Cannot force it into graphical. /dev/sdb is a disk with APM and OSX 10.5.8
on it. Logs suggest that it fails running gtk as well. Will try pulling /dev/sdb off. it fails the same way
selecting both Standard Partition and the (default) LVM. /dev/sda is a GPT-partitioned disk with EFIPartitionByMacOS, two ext4 and one swap part.
