Makes sense at that time. 

Nowadays kdrive doesn't seems to be a solution if I refer the the
thread in the Xorg MailingList. ^^

It appears that kdrive rendering method KAA has been removed because
EXA is much better.

Well, in the case of openmoko, this would mean changing the driver for
it to work with xorg. (nearly coding a new driver). On the other hand
this would mean a modular X server, with graphic drivers loaded as
needed, which means broader support without having to compile a X
server per device (as kdrive is compile time configuration). That would
correct some bugs I saw about keyboards not recognized by Xglamo and so

Anyway seriously thinking about migrating to Xorg is not a bad idea
itself but would mean a lot of work from openmoko because the community
cannot help without the specs... too bad...
