I wouldn't bother cutting  your cable.  Right now, the neo will only switch
to 500mA charging when it is successfully enumerated as a high-power
device.  The only way you'll get it to fast charge from a power-only source,
will be to change the software to something like you mentioned.  It
shouldn't need to take 30 seconds though.  Once the neo attempts enumeration
(by pulling up on D+ with a 1k resistor), the host should issue a usb reset
(single-ended zero) within 500ms.  If that doesn't happen, there is no host.

I have tried charging from other methods (generic cigarette-lighter to
mini usb, solar cell, crank charger) and none of them currently work
for fast charging. They may work for the slow charge, but the slow
charge is too slow to be useful.

The wiki says the neo "could" do a fast charging from these
non-host-computer usb ports by trying to pull 500mA when the host does
not respond for 30 seconds, but as of about a week ago, the
development image does not implement this trick.

I might cut open a usb cable and put in the pull-down resistor to see
if that works.
