WELL, my experiences so far:
- With the Intel on board controller it don't work. This controller accepts no mode lines
but only the modes stored in the BIOS - and those won't work tith the GDM-5410 monitor.
- The monitor seems to support multiple frequencies, but many modes work pretty poor. With
another PC (my old one) and a trusty Matrox G200 card I managed to get one mode (1280x1024@76 Hz) working.

Open questions:
- There are tools like get-edid+parse-edid, ddcprobe etc. which query a monitor via DDC about his capabilities.
Are there ports of such tools to Solaris/Sparc? I want to use the settings on the SUN WS to get other nice mode lines,
too.
- Failing that, how can I get the "predefined" set of nice modes which work for the SUN? (for example a 1600x1000 mode I'm using right now).

Not THAT simple :-(
