So, I finally got my old Grundig TV (ST 84-896 NIC/TOP) working with GroovyArcade and a Radeon 9250!
After trying out more or less every combination possible going from DVI or VGA to SCART (and failing badly each time), I finally found this ready-built cable on eBay which works great: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=330797220531 (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=330797220531) (there is also another version without audio from the same seller, "arcade8bits").
Two points I found worth mentioning:
1. I need to use the H9110 monitor preset in GroovyArcade to get a stable picture. With both PAL and NTSC, the screen just keeps rolling. A bit strange considering this is a PAL/NTSC compatible TV?
2. It was never possible to get this to work with a Radeon HD 2600, using exactly the same cable and selecting all DVI/VGA options at boot-up.
Regardless, it works now so I'm happy. Is there an official way to make a donation to the GroovyArcade project?
BTW, 33" is quite large when you're standing right infront of it... :o

Pictures please! 33" sounds mighty! Congrats!

Thanks for moral support! Here is a screenshot from the Sketchup model, the cabinet is almost 2 meters in height (well over 6').

Being a Swede, I felt the urge to build the cabinet only out of IKEA furniture parts. (Or, rather, I had some stuff from IKEA lying around that I didn't need.) ;D
I will post some photos further on as soon as things become more presentable.

I always recommend using CGA, GENERIC or H9110 instead of the PAL/NTSC because these are too narrow to be useful at all - one guy here reported his Nokia tv only worked when using the PAL settings, but that's very odd - anyway it's strange that the PAL/NTSC settings didn't work at all, as they are 'contained' in the wider H9110 setting.
2. It was never possible to get this to work with a Radeon HD 2600, using exactly the same cable and selecting all DVI/VGA options at boot-up.
Please give me some details, black screen? This card should work indeed. Unfortunately I don't have a physical way of doing regression testing for all chipsets each time the kernel is upgraded, but I'm pretty sure this card worked at the time the original patch was done by bitbytebit.

Hi, thanks for the quick response. I tried again with the HD 2600 and during most of the attempts the TV wasn't able to sync correctly. However I finally managed to get it to work using the DVI port farthest away from the motherboard and selecting the "DVI1" option at boot-up.
However all games run very slow with the 2600 compared to the 9250. Also the standard MAME menu is almost impossible to use because there is a lag of around 2 seconds from holding down a key until anything happens. (I can't use the AdvanceMenu+ due to the Illegal Instruction issue reported elsewhere.)
Only positive thing with the HD 2600 in combination with my SCART cable and TV is that gasetup runs in true interlace mode but on the 9250 the TV shows it as progressive but still flipping between the two interlaced frames (looks really strange).
