Well, not really, as it builds fine, but fails with the "Output LVDS
enabled but has no modes" message from master to 2ebc7d32; but doesn't
compile for older versions (tested both f6f79eb62 and 2.7.99.901),
where it fails with this error:

  CC    i830_dri.o
i830_dri.c: In function ‘I830DRI2CreateBuffer’:
i830_dri.c:224: error: ‘struct <anonymous>’ has no member named ‘format’
i830_dri.c: In function ‘I830DRI2ScreenInit’:
i830_dri.c:422: warning: assignment from incompatible pointer type
i830_dri.c:423: warning: assignment from incompatible pointer type


For kernel mode setting I will first have to make some free space on
my disk, hopefully this weekend.
