Thanks. I figured that after reading a lot of threads. (And thanks for
your other answer.)

I hope, you have seen my message to linux-fbdev-devel [1]. I will try to
do what Krzysztof suggested, but will have to read more about that.
Maybe we get it into Linux kernel 2.6.30.

Should we continue discussion about this on linux-fbdev-devel, that
means, can subscribe there?
