Having said this, what IS a "known good" snapshot?  :->

Is the glx-4 source tree usable enough to get things kick-started, or should I 
be working out of your rsync-ed stuff?

If it were me, I'd be forcing the driver into the PDMA mode (i.e. You fill 
DMA-able buffers, but you have the CPU MMIO the buffer's commands instead of 
ask the GPU to DMA it to itself.).  A failure in PDMA indicates a failure in 
the whole driver code or the server itself.  Hopefully, in another couple of 
days, I can manage to get one of my machines that has a Mach64 in it back 
into service enough to test things and maybe give you all a helping hand for 
at least that chipset...
