There is a architecture variant for MontaVista (older Hard Hat - SBS "K2") for the MPC7410 and I have been running it. I have reason to switch to the IBM part (it is known to be radiation tolerant for space applications). When I use the same boot image on the PPC750L the system hangs during the bootstrap process. (transfers to common routine to decompress the kernel, reports successful decompress, then no more serial output). I don't come from the PPC world and do not know the lineage of these chips - in fact don't know the difference between G3 and G4... Is there someone on this list that can be so kind as to give me a technical summary of the differences between the PPC750L (G3) and Motorola MPC7410 (G4) so far as LINUX operation. I assume some portions of the low level setup (cache, memory, serial port, ...) are different between the two chips. I can ferret out and fix it, but I would rather like to avoid becoming a complete expert on both parts...
