the latest git code of radeon driver will set big modes that beyond ATI
resolution 1280x1024@75hz at32bpp as well as 1600x1200@85hz at 16bpp are not
pruned by the driver.these modes are beyond ES1000 can support at 200MHZ and
will lead to uncertain status.
Acoording to chip spec.At 200MHZ,ES1000 cannot handle modes that higher than:
please refer to bug #5766 to get detailed information:
the root cause of this bug is the driver enlarged the pixel clock range of
es1000 by changing the empirical pixel clock max value in radeon driver, thus
add some big modes to the valid mode list.
I suggest change back the original pixel clock range of ES1000.
patch will be attached soon.

Change the empirical value back, limit pixel clock to meet memory bandwidth limits
Yes, I pointed this out on several occasions. Henry, do you object to this change?
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
