Just curious, is this a common problem with Quicksilver processors in
Digital Audios?
I have a DA 533 with a QS 933 processor that I am getting ready to make
the jump to 10.4 on, currently running 10.3.9. While I do have a hacked
G5s Radeon 9600 so I can run Core image, I am concerned about the
possible performance hit without the L3 cache.

Ron,
If you have any expertise in the depths of firmware and X etc, you
might take a
look at the CPU Director log. I'm not at my machine so I can't direct
you to it
but it is referred to in CPUD docs. This log shows what CPUD is
looking for and
can't find on our machines.
I've been curious to know what Quicksilver machines do differently
during bootup
to make that l3 cache available. I doubt it is in the sequence you
see when
booting with "verbose" enabled. That's where the CPUD log comes from
and that
is set by the operating system, not open firmware. It must be in the
firmware
stuff that comes before. I've often thought that there's probably a
firmware
line or two that would get it going. I've looked for Quicksilver
firmware
scripts but have had no luck. (You can read the script in the
firmware upgrade
for the DA, but there is no such upgrade for Quicksilver.)
On the other hand, CPUD in os 9 sees the cache. Sonnet Cache in
Panther did
too. So there should be a way to get it up without modifying the
firmware.
Even without the L3 cache, I like the 800 Dual.
