Which is clearly painful, and way overkill.
First you asked the wrong question looking from an initrd with a 64bit
user space. Even for a 64bit kernel you don't need a 64bit user space
and 32bit is smaller and more common.
Second you looked in the wrong place.
What you want is: http://kboot.sourceforge.net/
The intro page lists kboot-9 as being only 39K. I think that is just
the kboot part but it might be the entire initrd. Using uclibc I am
certain it is below 1M. Unfortunately I haven't had a chance to build
it yet. (Sorry Werner).
Check it out just skimming through the documentation it looks like it
has already surpassed FILO in capabilities.
