Right. I mentioned that in another bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=12494

The problem is that if you have a configuration under 2.6.28 without
CONFIG_FB and just call make oldconfig, or even make config and don't
know that you loose the DRM. And I was using make oldconfig (there is a
graphical config?? ;-))

There is that other bug 12494 mentioned, namely due to the disappearance
of DRM the brightness adjustment on my vaio z11 stopped working.

So maybe there should be a select FB or so under the CONFIG_DRM option
(not that I actually can program Kconfig).

Best wishes
