Hello Larry,
I think that problem isn't in the driver. There are several more probable
effects.
1. Problem in hardware. Can you test your software on another HW? What is
your result?
2. Highly loaded system. How many process in your system? I need output of
(with both Pg.flatdc and Pg.i830 drivers):
# sin ar
# sin ver
# sin ti
# sin ir
# sin in
# show_pci -vvv
3. Error in software. For instance, widget which implement of a mimic of a
plant may be not optimal.
