Thanks, that hint was helpful.  I have drummed up a patch (attached) 
that replaces some use of the UINT16LE_TO_CPU(), etc., macros with 
generic interfaces from the Xserver's compiler.h header file.  Now works 
correctly on RV610 video card on an Alpha XP1000.  Have also verified 
that the driver still works on an RV710 card on AMD64 architecture.

The patch applies cleanly against the 6.12.5 branch and also upstream 
git master.

Alex: may I presume that you will handle getting it upstream for review 
and hopefully acceptance into the fdo git master.

Cheers
Michael.
