I think you should try another monitor if at all possible. Perhaps your
monitor just goes into power-save mode with an incompatible signal. On
mine, it pops up a message that asks me to set my video card to "2560 x
1140 60Hz" which, according to the dmesg, it should already be:

radeondrm0: 2560x1440

My xrandr shows the 2560x1440 mode at 59.95Hz, I'm assuming that's close
enough to 60Hz that it should work? Or could that be the problem? The
highest I can get working is 2048x1152.

Screen 0: minimum 320 x 200, current 4096 x 1152, maximum 8192 x 8192
DVI-0 connected primary 2048x1152+0+0 (normal left inverted right x axis y axis) 553mm x 311mm
2560x1440 59.95 +
2048x1152 60.00*
1920x1200 59.95
