Are you using the stock Aurora 1.0 compiler? I'm pretty sure gcc 2.96
will chew up and spit out 2.6.*. I think 2.6 needs gcc 3.2 or greater.

No, I'm pretty sure thats bad. I've never had to do that in my test
builds. sparc64 is actually in pretty good shape in 2.6.

Well, you probably want to boot with -p to get more debugging info at
that stage, but the issues are almost definitely related to the compiler
if you're using 2.96.

sparc/sparc64 has never had bzImage as a valid target. In fact, I'm
pretty sure that x86 is the only arch that does. sparc doesn't need a
compressed kernel, because it has to be uncompressed into memory before
booting anyways. In 2.6, you can do "make image" instead.
