According to git bisect:

19d77d6cfa384142cc6ab4d9b3db4b28cefb6f19 is first bad commit
commit 19d77d6cfa384142cc6ab4d9b3db4b28cefb6f19
Author: Brian <bri...@tu...>
Date:   Tue Sep 18 19:29:26 2007 -0600

    temporarily set the FRAG_BIT_FOGC bit in InputsRead when fog is enabled
    (cherry picked from commit 63be96bdc7e9f388a5c49295bd7e150462fd003a)


The attached patch gets tunnel running here, but it still complains:

*********************************WARN_ONCE*********************************
File r300_state.c function r300SetupRSUnit line 1756
Don't know how to satisfy InputsRead=0x00000008
***************************************************************************


I think FRAG_BIT_FOGC needs to be handled in a couple of other places as
well, but I'll leave that to Corbin or Nicolai or so. :)
