Compact flash on mpc8349eITX

I'm trying to get the compact flash up and running on an mpc8349eITX,
and am continually running into issues where the IRQ is not processed,
and the mmio commands are not getting response. At this point, I am
starting to suspect a HW issue, but I was hoping to verify that I am
using a known good kernel configuration.

Has anyone successfully communicated with a compact flash device in true
IDE mode on the MPC8349eITX? If so, do you happen to know the kernel
configuration and/or revision?

I appreciate any help, as I am really getting stuck here.
Regards,
Sam
