I guess this question is somewaht outside the crossgcc mailing list ...

It would rather belong to "Linux from scratch" or whatever. I am very 
novice in this area but I nevertheless install customized Linux kernel 
versions using the Crux distribution (http://www.crux.nu). During the 
(painful) installation where I had to troubleshoot the boot image 
generation process to the greatest extent, I looked at the crux 
scripts/makefiles/... that created the required initrd.

Maybe that would be a starting point, in case no more educated response
comes to you.

The official Crux project has host==target but there are a  few more 
configurations with some volunteer efforts. Also don't expect much 
assistance from the Crux mailing list: this basic distribution is not 
meant to be novice friendly.

Hope it helps a bit.
