How does kos handle PAL mode when DM_320x240 is set? Does it center the image on the pal screen, and is the buffer still 320x240 or does it expand to 320x256?

And, can most PAL TVs properly display a PAL 60Hz image?

Would it be better to specifically set DM_320x240_NTSC or DM_320x240_PAL?

I found flashrom_get_region(), anyone know of any problems using this? It's listed as experimental.

This I actually do know: Yes, most PAL TVs can display a 60Hz image. I got a TV from the mid-70s and it is capable of displaying a PAL-60 signal.

Regarding your other questions, this might be a good source for this kind of information:

Even though this has been bumped by quite a bit...

Generally in modern KOS you don't have to specify the region unless you want to specifically use the expanded portion of the PAL pixelspace. If you want to use the flashrom to get the region, then what you'll want to use that for generally is just to make sure that your timings are going to say the same (so if you have a "every 60 frames do this" counter, you might want to set it to 50 or whatever).
