Disabling DRI will be unpleasant.

The option allows for explicit symbol visibility (with an option to hide all
inlines). The actual cause of the ATI + DRI + gcc + MythVideo crash is that
when the DRI layer is loaded MythVideo finds a chunk of the wrong
std::vector<int> implementation, the one in ATI's DRI layer, the one that
uses an older libc. It finds this because the promise of symbol versioning
is more lie than promise (template instantiations are not versioned).

When you build Myth (from SVN) just add the --enable-symbol-visibility
option when running configure.
