Images for different devices usually differ in kernel (and modules),
plus some other minor differences (minor by size of differences, not
by the effect they produce). Having a single installation image is a
great aim for the future, but for now we just produce device-specific
images.
To add htcalpine support to Angstrom, there should be a device mentor
for it. Mentorship includes regular and consistent testing of provided
releases, working with other mentors on solving issues in
general manner (comparing to device-specific hacks), submitting
patches, collecting feedback for users, etc. If you think you're
interested, the first step would be to try to build htcalpine image,
and report if its buildable - we'll add it to autobuilder then, and
you'll be able to proceed with testing official builds.

You'll need to provide patch for irda-utils. This is one of those small
by size, but quite noticeable differences from other machines.

This is "normal", feel free to ignore them. (Comparing to
issues due to under-developed kernel you report, these are just
harmless).

As recommended, try re-making the driver based on ts-adc.

There's no "Alt" on any PDA-style device. Having such a mapping for
"Contacts" button is wrong.

There's only now appears something to operate camera on kernel level,
so no big loss.
