fyi, for the time being, I've already kicked out the kconfig/makefile
splitup patches..

I'll go ahead and pull in the hdmi symbol rename patch, since that is
a sane thing to do.  I'm less sure about splitting things up into
separate .ko's.  And I think having the .ko name not match the drm
driver name (ie. what is passed in to drmOpen() in userspace) would
cause issues since libdrm could try to modprobe $drivername.ko.  (I
*think* that only matters in the non-udev case?  Which is at least not
a common case, but breaking userspace is breaking userspace...)
