It doesn't have to be ELF, I do it now on x86 for splash images. From /boot I load a .png, .jpg, or .bmp and add it to the module list but mark it as BI_MODULE_IMAGE (instead of BI_MODULE_ELF). I can then grab the blob from the kernel -- see arch/x86/x86/x86_machdep.c:module_init_md()

Can't make one of those without an ELF toolchain, right? The basic idea's about right, but I actually need something less sophisticated in its packaging -- a way to just give the kernel the address of blob-of-stuff the bootloader's dropped into place for it, so the entropy pool code can just take it and prime itself.
