I'm not aware of any tool in gentoo right now that x-compiles and then 
makes the flash image. Mostly we all merge into an alt ${ROOT} and then 
go run genext2fs/mksqushfs/mkfs.jffs2 or whatever suits your needs for 
the type of flashable image you are creating.
The gnap project does do building, merging and dumps out a flashable
image when it's all done. But afaik gnap is mostly targeted at native
compiles vs x-compiles.

The qmerge util from portage-utils is an ipkg/apt* work alike.

Provide the tools & development environment for users and let them 
figure out what's best for the device they own.
