Ok. I've spent a while trying to clean up the patchset and work out what was required and what wasn't for the kernel. These are now all up at:

http://the.earth.li/pub/e3/2.6.15/

I've included a pre-built kernel, a version of u-boot that has the machine type set to the Delta and a rootfs that includes some flash tools. Oh, and has the fix for the command line parsing stuff.
