People keep saying that but really, are you sure that openmoko goals
exclude proprietary software?

Linux is a perfectly free operative system but support for proprietary
software isn't discouraged. Think of Oracle, Opera, vmware to name a
few. In fact, one could argue that an open platform that makes
proprietary development expensive is less free than a closed platform
that makes proprietary development (as well as free development) free,
so I think you are very wrong about this.

FIC is a company after all and I'm pretty sure that to them, the
non-free nature of qtopia for proprietary usage would be a concern but
that is good. In fact I would prefer qtopia as a developer but I'm
willing to use openmoko, I really want.

I think you are confused about the framebuffer thing. A frame buffer
is always used, it's used by X too. (You are taking about the *Linux*
Framebuffer, a particular feature of linux). And yes, X adds an
overhead, that's why there are projects like FBUI or directFB. These
people aren't lunatic or morons, they started such efforts
specifically to remove the X overhead and have something as responsive
as Microsoft and Apple have. This is very well known, so stop
pretending that it's not an issue.

It's either one of the following:

1) Application asks to draw a line and waits. X sees that request and
uses a driver to draw the line, then sends confirmation. Now the
application waits and when the confirmation is received it's ready for
the next operation.
2) Application uses a driver to print the line.

Note that in the second option we are already ready for the next operation.,,

Which one would you choose for performance? Apparently most of the
phones are using the second. The mind boggles...
