Doesn't the Gallium3D software driver support geometry shaders on Linux?

See this article:
A 30,000 Line Patch For Mesa Brings Geometry Shaders (Sept 2009)
http://www.phoronix.com/scan.php?page=news_item&px=NzUzMw

Extract:
"Zack's Geometry Shaders support comes in a patch that's over 30,000 lines
of code and touches many different parts of the Mesa 3D stack. However, this
new support is considered "basically working" (bugs may be aplenty) and the
only driver
implementing this geometry shading support is the Gallium3D software
driver."
