Output from the above mkelfImage command.

Both in kvm-0.66 with Plex86/Bochs with Etherboot-5.4 and a Geode LX 
coreboot + Etherboot-5.4 [1] the kernel begins booting after downloading 
this elf.ltsp file, however it gets stuck at this line:

checking if image is initramfs...it isn't (bad gzip magic numbers); 
looks like an initrd

At this point SysRQ doesn't seem to work so I can't get any more 
information.

I suspect it is something about this very new kernel that is breaking 
mkelfImage?  I tried my mkelfImage binary with a 2.6.17-based Ubuntu 
kernel and initrd and it seems bootable.
