I'm afraid I cannot answer your question, since I'm not really a lcd4linux dev,
but as someone packaging lcd4linux for Fedora, and following this list for
quite a while now, I can tell you that the lcd4linux project is not really
actively maintained atm.

I think it is great that you want to improve support for the axp dpf-s, I
say go for it!  I'll surely happily add the patches to the Fedora packages,
even better would be if someone (maybe you) would revive the lcd4linux project,
if you're interesting try to see if you can reach the original admins, and if
they want to make you an admin for the sf project, then:

1) cleanup the axp driver
2) look at all the patches which have been posted on the list / are used by
distros and add them
3) prepare a new release
4) put a tarbal of this release on the downloads part of the sf project
5) ???
6) profit !

:)
