Nowhere do I see a description about the specific problem that has arisen in 2013 with the proper information (terminal output, dmesg output, lspci output, xorg.conf file, backtrace, etc). As suggested on the Launchpad bug report, I would try compiling xf86-video-sisimedia with the Archlinux patches applied: https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/xf86-video-sisimedia They have put a large amount of effort into keeping this driver working and have updated the patches in 2013.
If those still don't work, get your hands dirty... if any particular strings appear in error messages, find those strings in the source and figure out what function is failing. Then compare the execution of the broken copy to the last working copy you remembered. If the API of some dependency changed, use git bisect to repeatedly compile the kernel or the Xserver until you find the exact line of code in the dependency that made the difference. Hacking the driver might sound hard, but it's not so hard that you have to pay someone to do it.
