 too much power.. 4.7 watts to do video playback is far too
uncomfortable.  5.2 watts and the power will be hard-cut without
warning by the Housing's external PMICs (current limited to 1A @ 5V).

 but, more than that: the reason why i'm not including the OMAP5 range
is because Texas Instruments refuse to allow access to it.

 the only reason that the pyra team is allowed access is because of
the big splash and P.R. that went into the pandora, they were
permitted access to the OMAP4.. thus the relationship is
pre-established and they could gain access to the OMAP5.

 for everybody else, the OMAP4 and OMAP5 is considered
"mass-volume"... and is also BXPA "Weapons-Grade" Export-restricted...
despite the fact that it's manufactured in Taiwan and that boards are
usually made in the Far East.

 TI have .. err... bureaucracy problems, shall we say.
