it's kind of hard to say.  i see the lcdon/off, bkon/off much like the
"erase" command.  it's more or less universal for anything that supports
LCDs, but the actual implementation is very board specific.  kind of
like flash.  (noting the large number of specific flash implementations
in board directories.)

it's no difference to me either way... i'll go ahead and change my 
implementation.

in general, that's a policy i understand and agree with.  in specific,
though, i implemented the function when i was trying to debug why the
drawing of the test pattern wasn't working.  directly doing a memory-
modify and having to do the RGB565 encoding mentally was tiresome :)

i guess i'm proposing that this be the only real random drawing function
for just this purpose.  debugging the framebuffer is tedious without it.
if you'd rather not see it, that's fine -- i can keep it sitsang specific
as an additional patch people can apply.  i don't want to bolt in all
the random draw functions you'd expect in a GUI.  just rectangle solid
blobs.
