Hello, Mark!
Sorry, for my late reply, I wasn't reading the mailing lists for a while
because I am pretty busy with hardware development.

English, please.
You are looking for the SM501 graphics controller working on the PCI Bus
on the MPC8540 as far as I got your mail.
Yes, the last status I got is that the endianess is an issue for the X-server
if the SM501 is on PCI. However there are patches for the framebuffer/X
driver environment which takes care about the RGBA's somewhere out there.
There are also accelerated native X drivers available but I haven't used
those. Additionally, we have the option to swap the colors in hardware,
just in case anything goes wrong. :-)

Yes. But AFAIK they have the SM501 on the Local Bus of the MPC5200 which
is a different thing. Check their hardware documentation, if available.
Maybe there are more updates in the meanwhile... Updates are very welcome.
I will have to investigate that further if I come back to the software
layer of my project.
Best greets,
Clemens Koller
