Sorry, but isn't that a pretty bad idea. If it is decided to go the
GGI way (or some other way for that sake), I think the chosen solution
should cover all cases. Having this as a config option would mean a
lot of duplicated code and at least to me it indicates that a given
solution is not good enough as it does not solve the problems (this
applies to any solution - I don't think we should have two console
systems in the kernel, except maybe for a certain development time).

We do not disagree on the video mode switching, its already in the
kernel (for some architectures).

If GGI ends up requiring 200KB, then something is definately wrong
with it in my oppinion. We should shoot for having one console system
and if that is too big to be used on the smaller machines then I
consider it to be broken, telling people to buy more RAM is not an
option and a config option is a very bad solution on the long term.

If this becomes the result we end up in a very unfortunate situation,
it would be like one should go and get an alternative TCP stack in
order to talk to some systems.

Sorry, but that is very wrong - kernel inclusion means that it will
solve a problem or provide a resource that has to be in the
kernel. Including a wrong solution is not going to do anybody much
good - speaking out of principle here.

Good, what really annoys me with the whole thing about GGI is that
whenever people bring iy up on linux-kernel it is always presented as
the ultimate solution we should just sit down and wait for. It may be
a good solution in the _end_ (I am personally still not convinced it
will be), however in its current state it is not.

I think Geert's got something on his pages, but currently the server
seems to be down. The code is mainly in the vger snapshots (the stuff
in the official kernel from Linus is not fully uptodate), take a look
at drivers/video (some of these drivers are not very advanced yet) and
drivers/char/fbmem.c.
