mkelfImage does that, actually:

mkelfImage is a program that makes an elf boot image for linux kernel
images. The image should work with any i386 multiboot compliant boot
loader, an ELF boot loader that passes no options, a loader compliant
with the linuxBIOS elf booting spec or with the linux kexec kernel
patch.	A key feature here is that nothing relies upon BIOS calls, but
they are made when necessary.  This is useful for systems running
LinuxBIOS
