I'm now taking a minute to compare the Openchrome SVN codebase with the code from Via as of December 2007.
diff -q viachrome/ openchrome/ Only in openchrome/: acinclude.m4 Files viachrome/aclocal.m4 and openchrome/aclocal.m4 differ Common subdirectories: viachrome/autom4te.cache and openchrome/autom4te.cache Only in openchrome/: ChangeLog Only in openchrome/: compile Files viachrome/config.guess and openchrome/config.guess differ Only in openchrome/: config.h Only in openchrome/: config.h.in Files viachrome/config.log and openchrome/config.log differ Files viachrome/config.status and openchrome/config.status differ Files viachrome/config.sub and openchrome/config.sub differ Files viachrome/configure and openchrome/configure differ Files viachrome/configure.ac and openchrome/configure.ac differ Only in viachrome/: configure_OpenSUSE10.2 Only in viachrome/: config_via.h Only in viachrome/: config_via.h.in Only in viachrome/: config_via.h.in~ Only in viachrome/: config_x11r7 Only in openchrome/: COPYING Files viachrome/libtool and openchrome/libtool differ Only in openchrome/: libxvmc Files viachrome/ltmain.sh and openchrome/ltmain.sh differ Files viachrome/Makefile and openchrome/Makefile differ Files viachrome/Makefile.am and openchrome/Makefile.am differ Files viachrome/Makefile.in and openchrome/Makefile.in differ Only in openchrome/: man Only in openchrome/: prepare-ChangeLogSVN.pl Only in viachrome/: README Only in openchrome/: release_notes-0.3.0 Common subdirectories: viachrome/src and openchrome/src Files viachrome/stamp-h1 and openchrome/stamp-h1 differ Only in openchrome/: .svn
Wow that is only the tip of the iceberg! I did do a little touch up to the openchrome files in an effort to enable panel mode for the P4M900, but it didn't work. I'm just not familiar enough with C or the codebase.
I also wish I had found this page earlier:
Its a blog by a video driver developer, and has a lot of good perspective regarding VIA's behavior towards the open source community.
