The above is now all academic since the current kernel boots to an oops
and instruction dump. The only way to get the kernel to boot is by
forcing a 32 bit depth on radeonfb. There is no way to get radeon KMS
(and consequently the radeon xorg driver) working as far as I can see.

Attached is a patch for yaboot-installer. It shows how easily this bug
could be fixed on an installed system by just using the vt.handoff=7
boot parameter (the same as Grub2 does). It also creates a recovery
option (the same as Grub2). This is therefore a low risk solution to
the problem.

A lot of the Apple PowerPC users will be using a radeon 9200 card or
something similar. It is probably worth pointing out that there has
been a kernel release note about these cards for a long time now:
"On systems with an ATI Radeon 9200 graphics card the system will boot
to a black screen. As a
I've also asked the X people in bug 1058753 if they can confirm what is

Changing bootloader is overkill for this problem, although if you are
interested I have written a guide to using grub2 on PowerPC
https://wiki.ubuntu.com/PowerPCFAQ#Can_I_install_grub2.3F . The
sticking point for grub2 is can it boot macos/macosx (neither or which I
have on my machine)? Or do you
vt.handoff=7 is only really any use in combination with the other
graphics setup that GRUB does. I suspect we could only do that if we
changed boot loader as well, which might be nice but it seems a little
late for 12.10 really.

With grub I always seem to have the boot option 'vt.handoff=7' added.
Just wondering if this should be added to the default yaboot parameters
along with 'quiet splash'? It seems to cause me to boot into 16 bit
mode which is obviously more desirable than 8 and makes ubiquity work.

Booting with the parameters 'live video=ofonly' got rid of the dithered
graphics, things look nice now. This also seems to fix bug 1040544

These are the current workarounds for radeon users:
1. Turn on KMS - the boot parameter video=ofonly should do this. If
this causes freezing then combine with radeon.agpmode=-1
2. Use the fbdev driver. To increase the colour depth use a boot
parameter such as video=radeonfb:1024x768-32@60. Ob

I've been experimenting with fbdev and the openfirmware framebuffer. It
is not good. Instead of 8 bit graphics it is more like 4 bits.
Removing radeonfb is going to be even more painful for those that can't

Radeonfb shouldn't be removed without the boot message on the CDs being
updated. Otherwise we are going to have a lot of people with frozen
computers, not knowing what is going on. They will need to reduce the
