I have LG Flatron F900P CRT monitor. X drivers work fine, nouveau KMS works fine but Radeon KMS selects a videomode that is out of spec for monitor. This is not a regression - this hardware combination has never worked for me yet with radeon KMS. The result is same for Radeon 7000 (RV100, currently installed) and Radeon 9200 series card.
Umm, I guess I forgot one important aspect. When X comes up, it finds a good video mode and gets a picture. It's just the text consoles that have no picture.
In the console, it tells it's using 352x132 console. This translates with 8x16 font to 2816x2112 and 9x16 font to 3168x2112 if I calculated the right thing.
Running fbset remotely verifies this:
# fbset -s </dev/tty1
mode "2816x2114" geometry 2816 2114 2816 2114 8 timings 0 0 0 0 0 0 0 accel true rgba 8/0,8/0,8/0,0/0 endmode
So it decides this modeline is usable for the console while it is not.
Ah, ok. yeah, that mode has a much higher clock than those chips can handle. Where is that mode even coming from? I don't see it in the EDID. The attached patch should filter out that mode.
