Yes, that should work better, the toplevel vmlinux is a pure ELF file with
debug information included. Be careful though that you need the very latest
binutils-2.9.5.0.37, a current snapshot or a cvs checkout of binutils to
generate a 100% (?) valid ELF file, a bug in this area was fixed just
recently. Otherwise the ELF converter/loader may choke on the debug
information. If you use gcc-2.95.2 (which you really should) to compile the
kernel, you can change the debug flag in the CFLAGS from -g to -gdwarf-2 to
get a lot more and very valuable debug information.
