The cable is actually about $10. Here's one:

As one review states, it obviously won't work without support built into
the device.  In another site a review states that the cable worked fine
for them.  Interesting.  This cable is intended to go from HDMI to VGA;
there are other cables that go the other way--VGA to HDMI cables require
special video card support obviously.

NVidia says the ION directly supports HDMI, Displayport, and VGA,
simultaneously (well any two).  Not sure what that means in the context
of the HDMI port on the laptop.

Yeah, that is a possibility.  Given the netbook is about $330, anything
more than $10 isn't really worth it.

Linux for power management, sleep, etc?  I run a myth frontend with a
little Revo, but I've never tried to sleep it before.
