Do you have a link?

The patch I've currently put together allows ixp400 code to compile
against *vanilla* 2.6.18.8. I'm in the process of testing in now. Once
I make sure it runs, I'll start moving the patch toward targeting the
mainline kernel.
I initially tried to make it compile against 2.6.23, but there were too
many changes to do it right. So, I figured I'd start with 2.6.18.8
(only because it was the closest gentoo stable vanilla kernel to the
version Intel/Timesys suggested using), then move up making small
changes along the way.
