Hi!

I would be glad if you try my patch and tell us if it
also works for you:
http://lists.opensuse.org/radeonhd/2007-10/msg00307.html

The key changes are:

in RHDLVTMAInit(RHDPtr rhdPtr, CARD8 Type)
 t this time */
-    if (Type != RHD_CONNECTOR_PANEL) {
+    if (Type != RHD_CONNECTOR_PANEL && Type !=
RHD_CONNECTOR_DVI) {

and later set the LVTMA_MODE to TMDS if we've detected
a DVI (According to the DVI Specs, DVI and HDMI always
use TMDS on the physical layer):

in LVTMASet:
-    RHDRegWrite(Output, LVTMA_MODE, 0);
+    RHDRegWrite(Output, LVTMA_MODE, lvtmaMode);

where lvtmaMode acc ATI docs:
0 -> LVDS
1 -> TMDS

I've basically changed not much else and it worked out
of the box for my setup (X1300+DVI).

I could not find any information in the ATI specs if
any specific LVTMA registers are also used in TMDS
mode or are only needed for LVDS, but it was already
2:30 in the morning ;) So there is for sure much room
for improvement, but at least X starts.

LieGrü,
strub
