--- Comment #16 from genstorm andreas.sturmlechner@gmail.com 2012-02-16 08:33:19 CST --- I guess those are the lines you were asking for:
trace:wgl:X11DRV_WineGL_InitOpenglInfo GL version : 2.1 Mesa 7.11.2. trace:wgl:X11DRV_WineGL_InitOpenglInfo GL renderer : Mesa DRI Mobile Intel® GM45 Express Chipset . trace:wgl:X11DRV_WineGL_InitOpenglInfo GLX version : 1.4.
Looking at the output I realized my fault - by rebuilding the mesa package I only touched the (8.0) 64 bit files. The Gentoo 32bit emul package right now does not provide gallium softpipe it seems...
