It's actually more complicated than that. Old kernel images started misbehaving from around 2.6.35-rc5 and any kernel older than that was OK. When I recompiled the older kernels with squeeze gcc (migh have been lenny gcc before, or different answers to make oldconfig), anything from current git down to 2.6.33 is broken with radeon.modeset=1 and works (I get window titles) with radeon.modeset=0. 2.6.32 works and has kernel modesetting enabled from dmesg but I think I did not notice screen going fbcon during boot... maybe it only used the modesetting when X started. So there are 2 different problems (maybe related), the new one above and the old one of not seeing some window borders when modesetting and acceleration are in use. Maximized windows do have borders. -- Meelis Roos (mroos@linux.ee)
