Here is an update on the status:
1) I tried installing the Xpmac.rev10 server that someone recommened in
the hope that that would fix the problem. Unfortunately it didn't as
five minutes ago the system locked up yet again. This seems to suggest
it may be kernel related rather than X related.
2) I recompiled my kernel wth the "Magic Sysrq" support in it. This
seems to work more or less as designed. However when the system locked
up as before the "magic sysrq" key did not work at all meaning I had to
reboot without being able to shut down properly. This suggests to me
that the kernel had itself crashed.
Exact same thing on my previously rock solid x86 box - only change was that
I'd just upgraded to XFree86 4.0.1 and kernel 2.2.16, from XFree86 3.3.6 and
kernel 2.2.13.
The behavior is identical - makes me wonder if this was the mmap() bug
that BenH previously mentioned, and if this was a cross-platform issue
not just isolated to PPC?
Okay so you get it on x86 2.2.16 and XFree 4.01
I get it on powerpc kernel >= 2.2.15 and XFree3.3.6
Any other takers?

Be frank and explicit with your lawyer ... it is his business to confuse
the issue afterwards.

I don't know if all this is really the same thing, but I have been
getting sudden X freezes randomly with all 2.2.x kernels when using
Xpmac. For me this was the main reason to switch to XFree68_FBDev where
I *never* got these with 2.2.x kernels. Now I am getting these freezes
also with XFree68_FBDev (some 3.3.6 version) when using 2.3.x or 2.4.0
kernels. I very rarely use xmms (but always netscape), and I get these
freezes sometimes when the machine is completely idle. Sometimes this
happens after a couple of minutes, sometimes after 3 days.
The symptoms are: Mouse frozen, no keyboard input possible, no
MagicSysRq, no X shutdown with ctl-cmd-del, no console switching, the
only key combination working is the ctl-cmd-power hard reboot. On the
other hand, the kernel and even X seem to continue to live at least for
a while. I can see messages continue to scroll down and hear downloads
or compilations making their disk noise. The one time I tried to ping
from the outside, I was not successful, but then it sometimes takes 2
minutes of pinging to wake the machine up and get a response even when
it is not frozen.
From my observations, I concluded that this must be a problem with the
keyboard and/or mouse drivers in X. But since this part of the kernel
and X ( I never understood why XFree has to have their own drivers for
everything that is already in the kernel) is worst black magic, rapidly
changing in incompatible ways, and since my machine (6400, ADB keyboard
and mouse, valkyrie video) belongs to an endangered species anyway, I
did not really try to understand what happens.
