Why not just make it a multiboot compatible image and load it via the
multiboot loader?

You can load a kernel from USB using the firmware's USB support or
grub's native USB drivers, and the same with loading via the network.
Though for loading from the network using native grub drivers rather
than an in-firmware stack (like PXE) or iPXE you'll need to use grub
from bzr trunk.
