My mistake. I didn't supply the version to mkinitramfs so it
loaded modules for the running kernel, not the kernel I had just built.

On my other machine, a couple of months back, that is what I tried to use
because there was documentation stating mkinitrd was obsolete. But
the image built by yaird couldn't be loaded and when I went back to mkinitrd
it worked fine.

I'm not sure that will work. I tried it once and it didn't work but I don't 
know if I missed some essential module or if its because it needs the
scripts that are also in initrd. 2.6.12 seemed to be the only kernel
source available from ubuntu, at least for breezy badger.
