Description Hui Yu 2004-08-12 14:55:52 EDT
This is for Dell server using radeon 7000m. Radeon driver has benn 
updated to support the special configuration of Dell server. However 
Dell reports TVDAC output RGB signal is a bit too high, need to 
adjust RGB voltage from ~800mv to ~760mv. See patch below.

Patch updated in 4.1.0-62.EL build, which will be released as
