some packages even force other optimizations without the user bein able
to change this unfortunately. -O3 is generally considered safe however.
I myself like to use -O2 in some situations still.

The message will be displayed no matter which version of the kernel you
have booted. It is to inform you there are problems with the kernel dri
stuff and the xfree86 module

NVidia has their dri drivers in a separate module since their drivers
are NOT OPEN SOURCE. wasn't it nvdriver? go look!

both seem to work in some cases. the kernel radeon dri driver is nice,
but you still need the xfree drm (or was it the other way around).

for nvidia I suggest disabling the kernel options and installing the
nvdriver modules, they are what you prolly want. the xfree86 ones are
nice too and open source, but not written by nvidia itself.

anyone more info?
