the same here.  I can now even confirm the same problem on a different
machine, a dual G4 450, running debian testing.

The actual problem seems not to be an infinite loop, but rather a very
long loop.   IF you wait long enough, it will eventually work.  A
significant delay (i.e. assumed long loop) is also observed while
loading any module.  Something like 10 - 15 seconds for every module
that I'm loading during startup (ipv6, tulip, dmasound_pmac, ...)

The machine is completely frozen during that loop, not even the cursor
is blinking anymore.

compiling the kernel with gcc 2.95 or 3.0 removes those symptoms.
