 it depends.

 for the mass-volume products it needs to be under 3.5W because that's
about the thermal passive limit when the case is on (including filling
it with thermal gel). the assumption is that there will be *no* fans
in *any* products.

 for the non-mass-volume products: without the case, the limit's 5W if
you use the 2 PCMCIA pins (0.5A max rating x 2).  if you use the
USB-OTG as well you get an extra 900mA potentially so in theory you
could go to 9.5W but that's entirely up to you if you choose to do
that.

 anyway, i'm just going over the power tree, right now, so i have all
the PDFs open.... adding up the max ratings from the EVB:

>>> 1.5+(1.25*1.6)+(1.2*1.2)
4.9399999999999995
>>>

 hmm, so it's pretty close.
