[Arm-netbook] Slowly but surely...

[freebirds at fastmail.fm]

ARMv7 is not on ARM's list of processors supporting TrustZone.
http://mobile.arm.com/products/processors/technologies/trustzone.php?tab=Why+TrustZone?

ARM needs to update their list and also include processors that support
virtualization extensions such as ARM Cortex A9 which ARMv7 has.

On the NewIt forum, I asked simple mundane questions such as whether an
USB mini keyboard, mouse and LCD screen will work with a SheevaPlug or
will there be driver problems. NewIt sells the sheevaplug and dreamplug
preconfigured with a mimo driver for the mimo touch screen. Rebranded
MimoPlug is sold on Amazon. Since I do a lot of typing, I need a
keyboard. The NewIt forum does not have much activity. It isn't just my
posts that do not receive much responses, if any.

I read complaints of Sheevaplugs and Guruplugs over heating on several
forums. Freedombox Foundation's mailing list explains how Globalscale
designed DreamPlug not to over heat.

Yesterday, I found a photograph of DreamPlug's motherboard and emailed
it to two geeks asking if they can desolder the wifi and bluetooth.
