Makes sense. I'm impressed you actually manage to get a modern kernel
in 1.5MB and have it boot up a (mostly) full distro. I think we have
in the past dropped a subarchitecture from the kernel when it turned
out its defconfig could no longer fit within the 2MB of flash it
has.

Ok. As I mentioned, I believe OpenWRT is really the playground for
the remaining ixp4xx users that are doing new installs.
