Driver bugs which are found in a recent kernel can be reported at the mailinglists or at http://bugzilla.kernel.org/. Usually it is more effective to report a bug at a mailinglist instead of the bug tracker. That way, more people see the report right away when it is posted. Bug reports can still be copied over into the tracker later if they don't appear to be fixable in the short term.
