xkb for myanmar

Hi,

I'm running unicode compliant font project for myanmar(formally known
Burma), currently working on burmese script, unicode 4.1.
With this project, i also mapped the XKB align with the font. But it's still
on going and not complete yet. It can review at

I have a few questions:
1) How should i contribute to X desktop system?
2) XFree86.org or X.org is the same? If i contribute xfree86, is it same
reflection to X.org?
3) For contribution, if GPL is not compliant, which license should i include
or so that i can update?
4) Any other instructions for i18n new comer..

Thanks and regards,
Victor
