Hey Soeren, thats my website you cited there (although it's official home is now http://www.johnleach.co.uk/documents/powerpc/ but it's the same content). Just to update you, I still have the yellowy tinge on an external analogue monitor with 2.4.21-rc2-ben0 and the updated drm-trunk code (giving me a radeon.o kernel drm module of version 1.8.0.) I'm unable to test a digital flat panel at present. If anyone is interested, I took a screen-shot of the yellowness which subtly does not affect the entire screen all of the time. I thought it strange I could actually take a screen-shot at all that still looked yellow on a normal display. http://www.johnleach.co.uk/documents/powerpc/dualdisplay-ss.png My friend has the same problem with his Radeon 7500 (mine is a Radeon 9000).
