AMD64 is the same endian as x86.  I think you're going about trying to find
the problem the wrong way however, by making random guesses of what the
problem is, and then hunting through the code to find instances of that
problem.  Kindof like taking random pills from the doctor until you find
the right ones for the illness you're having.  ;o)

Looking at the raw facts of the problem, I would say that it is either a
generic driver bug on a certain model/revision of the 9200 variant you
have, or possibly even a hardware bug, but I'd lean towards some kind of
driver bug which requires a fix specific to the chip you have.

There are other possibilities also, but rather than guess, what is more
important is to be able to reproduce the problem easily and debug it from
there to find out what is going wrong and where.

Configure X for a configuration that doesn't work, and then attach the config
file and X server log file from that configuration as bugzilla file attachments
using the link above.  Also please provide the output of:  "lspci -vvn".

I've got an official ATI Radeon 9200 Pro here for testing/troubleshooting, but
no other variants or brands.  Once I've got time available, if nobody else
has confirmed the issue, I can try to reproduce.  It'll probably be a month
or two before I'll have time to investigate though.

I'll CC'd Hui Yu from ATI once I figure out the email address he uses in
bugzilla, in case he might be aware of such a problem.  Might be a good
idea to CC some of the other Radeon developers/contributors too.

Thanks Don.
