first, you'd need to reconfigure that linux running in a VM to run in
whatever hardware your embedded platform provides (network, disk, etc).
second, you'd not only need a new kernel, but also any usermode packages
that are -i686 or -i586 would need recompiling. there's more than you
might think.

that will run on nearly -anything- with very minimal resources. the
standard version fits on a 50MB live mini-CD (those credit card shaped
things).
