I had the following assumptions:
- The MPC875 will try to boot from 0xfff00100 due to my HRCW settings,
which cause MSR[IP] to be "1". 2. The whole memory is tiled with the first 64K of the flash due to the fact that OR0 is 0x00000ff4 when the board boots, which should mask out
Did you read the MPC8xx User's Manual about how the processor comes up from reset? Read it again, please.

And, just to add my 2 cents, you should look at your debugger configuration. Your debugger most likely is writing to registers to set your processor up so it can load and run programs. This includes writing to the BR and OR registers. Look at what it is doing for initialization, compare that to what you are doing, read the processor manual, and understand it all. That is the path to enlightenment (or at least blinkin' LEDs).
