Thanks a lot! The following line under Section "Device" also
solved my problems with the Sun GDM-20D10 monitor and Blade 100:
Option "reference_clock" "28.636MHz"
I had tested every modeline I could find for the GDM-20D10, and with all
kinds of sync settings, but I never got the monitor sync with the ati
driver. Using the wsfb driver instead worked fine, but then I was
limited to 8-bit graphics in 1152x900 (or something like that).
Now I can choose between lots of resolutions, and all in 24-bit.
