Hi Doug,

The real target is "make trampoline", which will generate kernel.tramp,
kernel.tramp.bin, kernel.gz.tramp and kernel.gz.tramp.bin.
kernel.gz.tramp.bin will be I think what look the most like zImage, as it's
a raw binary, able to uncompress the gzipped kernel embedded.
Unfortunately, you can't, afaik, do it with the "buildkernel/installkernel"
method, so you'll have to use the old config + make depend all method.

Cheers,

Olivier
