[Fedora-livecd-list] liveCD doesn't boot on IBM X Series Hardware

[msacks]

I am having a problem where after spinning a F13 or F14 LiveCD and
booting it on IBM X Series hardware.
If I test the same LiveCD on a different kind of hardware, it works
fine without issue.
If I test a standard Fedora LiveCD (non-spin) and boot it on the IBM
hardware, it works fine as well.

I know that the LiveCD I am spinning works, just not on IBM hardware
for some reason.
And I know Fedora works on IBM, because I've tested that as well.

What happens is the progress bar shows at the bottom of the screen
when it's booting, and then it just goes to a black screen.

Is there a known compatibility issue with IBM X series hardware and Fedora?

Is there a way to diagnose what the issue might be?

My next step was to start disabling certain packages in the spin to
see if something is conflicting on boot.
