 i have nooo idea, i leave it up to james: i trust him, he gets on
with it.  his english isn't very good, so i prefer not to quiz him -
he just make a solution work, i'm happy.

 well... tough for them!

 not good enough.  you can't go spending money like that, in advance:
that's completely unreasonable for you (and for anyone who wants to
have the possibility of a marvell CPU).

 tell them no way - no deal, asking them this question: how can we do
an open survey, asking people "ohh, because marvell will not tell us
the price, you must donate approx $20 each, for us to 'prove' to
marvell that we are worthy to use their CPU in the 100% free software
FSF-approved netbook" ?

 if that doesn't work, then tell them that lkcl said that they can
fuck right off :)

 yeah - but we can't do a survey asking people to spend money just to
"prove" to marvell how "worthy" we are.  ha ha.  very funny.

 for a 2ghz CPU?  they are taking the piss.  or, the yield is very
poor.  i assume that's a 45nm part.  ask them what the CPU speed is at
70 Centigrade, and how much power it consumes at that temperature.

 i bet you it is 4 to 5 watts ( but below 25 centigrade it is 1 watt ).

 yes.  that's one of the plans.

 whoo-hoo, that is just about ok - that will squeeze in, there is a
very thin plastic sheet covering the area under the SO-DIMM, so there
will be no electrical contact.
