I do have more suggestions to try, mostly directed to getting Xorg to try a 60 refresh instead of 75. Your display supports a vertical refresh range of 50-85. Every LCD I've ever used worked fine using 60, and using 75 instead if it was even possible produced no no apparent difference over 60.
http://fm.no-ip.com/Tmp/Linux/Xorg/xorg.0.log-m7ncd-os121-r7500.txt is a complete Xorg.0.log from my Radeon 7500 on 12.1.
http://fm.no-ip.com/Tmp/Linux/Xorg/xorg.0.log-m7ncd-os121-r7500-1600x.txt is a grep of 1600x from that same file. Note that each modeline appears to be a 75 refresh mode. Yet, the script excerpt
http://fm.no-ip.com/Tmp/Linux/Xorg/xfetch-dellLCD1600x1200.txt
from a running Konsole indicates via the xrandr command that only a 60 refresh is available and being used on my Dell 1600x1200 LCD.
So try first putting
video=1600x1200@60
on your grub cmdline in place of
splash=silent quiet vga=0x317
If that doesn't help, next use either xorg.conf and/or three files in xorg.conf.d/ to configure X to not try to use any 75 refresh modes. For the latter, redo as you did according to http://lists.opensuse.org/opensuse/2012-10/msg00259.html but remove the comment from the VertRefresh line and change the numbers on it from 56-86 to 49-66.
You can also try changing 'Option "PreferredMode" "1600x1200"' to 'Option "PreferredMode" "1600x1200@60"' or 'Option "PreferredMode" "1600x1200@75"'. Yet another thing to try is uncommenting the '# Option "DDC" "off"' line.
If none of above works either, try changing the 49-66 to 59-61 and try once more.
I tried the above but none of them made a change. Not exactly; after some setting after entering login data only a black screen started, that is I even could not log in. I cannot recall which setting of the many caused this.
If still no help, bring the thread to the opensuse-xorg mailing list after looking up how to create a modeline to include in xorg.conf or 50-monitor.conf to try first. Howtos for that are all over the web, though note I've never needed to use one in any Xorg version ever, with any LCD or CRT. The other list is more likely to draw attention from a developer who might be more help.
I will see whether I'll spend more time on this issue or just put in an nvidia card. This radeon was only a spare card until I get an nvidia card. However there is one thing I do not understand: according to lsmod|grep radeon the radeon module is not loaded either in 11.2 or in 12.1. Then which driver is working? By the way in my system xrandr gives the following: openSUSE 11.2:
