sorry for the delays, I'm currently for a week at my parents place and
don't read email as frequently as I'd usually do.  

I personally recommend switching to the 2.6.24 based tree before a
release, since it's much easier to do now than later.  The more you
deviate from more recent kernels, the harder it is to merge back later.

yes, unfortuantely I never implemented hardware accelerated framebuffer
for the glamo driver.  Theoretically there are only a few operations
that have to be implemented (for cursor and for bit blitting) and it
should be super fast even with console enabled.  Now that Xglamo is
around, it should be fairly easy to port this functionality into the
kernel.
