Strange, looks like the neither plls nor the palette regs aren't programmed
after resume.  Does forcing a mode set after resume help?  E.g.,

xrandr --output LVDS --mode 800x600
xrandr --output LVDS --auto

If not, do the following commands help?

sudo ./radeonreg regset 0x00000284 0x1bd34008
sudo ./radeonreg regset 0x000002d0 0x003c00a5

If that alone doesn't fix it, in addition, try:

sudo ./radeonreg regset CL:03 0x001c0007
sudo ./radeonreg regset CL:04 0x00010038
sudo ./radeonreg regset CL:05 0x00010038
sudo ./radeonreg regset CL:06 0x00010038
