 yyehhh... the bandwidth's just.... let's do the maths.  assume a
60fps refresh rate?  so 2560*1600*60*4 (bytes per pixel=32) we're
looking at 983mbytes/sec.

 i'd guess that 983mbytes/sec would utterly overwhelm most ARM
processors internal memory bus architectures.... and that's just for
refreshing the display - it's not even for *updating* it.

 so it's pretty hard-core.

 the current focus of design - because it's where the money is - is on
"IPTV" and "tablet".  do a quick scan of what allwinner sells: all
their products are either "TV" or "Tablet", with the occasional
"tablet-that-thinks-it's-a-smartphone" SoC thrown in.

 in other words, i feel that when tablets start getting 2560x1600
displays, and those become popular enough to catch allwinner and
rockchip's attention, we might start seeing SoCs that support that
kind of resolution.
