Yes, it's a different problem this time - the engine locked hard.

^^^^
These values on the left side are absurd - the DMA buffer is busted.
This means that either invalid data was generated or it was overwritten.
I vote for the former (attending the new vertex template code may be
buggy somewhere).

Ok, I'll contact you if make any advances here.
hmm.. ATI Xpert 2000 Pro? That's an R128... I'm sad we won't be able to
count with you anymore for the Mach64 development, but I hope you still keep
your insterest on the DRI development. Thanks for all the help you've
given, Felix!
