Using memmap=3D636K@0 memmap=3D255M@1M (from just naively converting the e801 numbers from the 2.6.18 boot) it appears to get past that issue and then panic because of no root filesystem (unsurprisingly as it's based on an allnoconfig config). Trying the same with the Debian Squeeze 2.6.32 based kernel results in it not panic'ing when unpacking the initramfs but there are many complaints about IRQ's happening and nobody caring and the system ends up shutting itself down due to timing out bringing up the root filesystem from the software RAID. I'll be away from email for a few days now because of the Easter holidays here, but I'll catch up when I'm back. All the best, and thanks to everyone for the help so far!
