Actually, I *believe* it didn't.  I honestly didn't get it to work at all
before applying the patches (I found the SIGNED_SAMPLES and
POKEYSND_BIG_ENDIAN defines after patching), but I did later on boot to
what I *think* was a kernel before the patches... I say "think" because I'm
not entirely sure I didn't overwrite that kernel with the new patched
kernel at some point during this whole process.. but I am fairly sure that
it probably would have worked the same, and that this problem has always
been there (ie, you didn't introduce it, AFAIK).. so it's either a problem
with the sound implementation in LinuxPPC or in Atari800... but, since
Atari800 is primarily developed for the Atari Falcon (m68k, I believe) and
not x86 (although x86 support is certainly more carefully monitored than
PPC I'm sure), I'm not entirely sure where the problem lies..

.ugh, sorry for the rambling.. I just got off work and it's 3am already so
you'll have to excuse me.. :)  But, if anyone who does know more about
kernel hacking than myself would care to make some attempt at building
Atari800 I would really appreciate it.. I could send the latest sources
(0.9.9h) plus the required roms to whomever is willing to try.
