The XFX Radeon r7-240a-clh4 and XFX Radeon r7-250a-zlh4 video cards do not seem
to be able to generate 3840x2160 @ 30 Hz video modes over HDMI, even though I
believe their hardware is supposed to be capable of this (~299 MHz pixel
clock).

At least with my se39uy04 39" Seiki television, the Radeon X.org driver happily
passed through the five 3840x2160 @ 24-30 Hz that the television's advertises
in its EDID modes to xrandr, meaning that driver thinks it can support those
video modes, but, if I select any of them, the telvision just says "mode not
support."  In comparison, if I make a custom video mode for 3840x2160 @ 15Hz,
the 4k TV displays that fine.

I am attaching a .tar.gz file containting /var/log/Xorg.0.log and logs of
dmesg, xrandr, xrandr --verbose for both cards (r7-240 and r7-250).
