--- Comment #6 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Yes, Gallium drivers have quite different shader compiler code from classic
Mesa side.

Blend function issue will be fixed in next version of Valley, it's a bug in the
demo.  If  you don't want to work around the demo bugs with environment
variables, you have also an option to patch Mesa:
http://cgit.freedesktop.org/~kwg/mesa/log/?h=unigine

(There are also patches floating around for allowing extension declarations
elsewhere in shader source, but they seem to get fairly quickly out of date,
and AFAIK they won't get merged into Mesa until Khronos GL specs have been
changed accordingly.  See e.g. patch mentioned in bug 71591.)
