Installer problems with 11.0-RC3

[Roger Leigh]

Up until now, my G4 Mac Mini has been running 10.3-RELEASE.  Today, I 
tried the 11.0-RC3 installer.  Two issues noted:

1) The colours in the installer are different than the PC installer. 
The background is a mid brown with yellow text.  An issue with the 
console framebuffer?

2) It won't boot after the installer finished.  It errors out while 
loading the loader:

     ofw_close devh=0x0

     >> FreeBSD/powerpc Open Firmware boot block
        Bootpath: /pcie at f4000000/ata-6 at d/disk at 0:
        Boot loader: /boot/loader

     Invalid memory access at %SRR0: 018011f0    %SRR1: 00003030

   and then drops to an interactive OF prompt.  Has anyone seen this before?
