v2.5.32 - v2.5.64+ Locks at Boot with Athlon Machine

[Jim Peterson <jpeterson@annapmicro.com>]

  I've tried versions 2.5.32, 2.5.59, 2.5.61, and 2.5.64, as well as version 2.5.31 and
  earlier on my machine.  Every version from 2.5.32 and above locks up after printing:

        Uncompressing Linux... Ok, booting the kernel.

  I've noticed there have been some significant changes in what I understand of the boot
  process at this point, but I can't decipher the assembly hardly at all well enough to
  try to investigate further.  Is there any place that I can acquire a set of the
  separate, unrelated patches that happened between 2.5.31 (which boots) and 2.5.32?
  I'm basically a trained monkey when it comes to debugging this kind of thing, so I'm
  going to have to try the old "back out a patch and see if it works" technique.

  My config file is pretty bare-bones, I've tried with and without the "mem=nopentium"
  and "noauto" kernel parameters (as dredged up via Google).  I've also tried replacing
  setup.S from v2.5.31, this just immediately reboots.

Any help would be greatly appreciated,
