I'm wondering if it makes any sense to build the various gallium hardware
drivers when not ./configured --with-driver=dri? (at the moment svga i915 i965
r300 are all automatically enabled) Does it make sense to build gallium at
all? (yes for --with-driver=xlib because we might want to use swrastg, but not
Attached patch makes --disable-gallium-r300 the default if not --with-driver=dri
