There are a lot of marginal VIA systems out there. Mostly due to really poor quality motherboards (I had several myself that ended up with leaking capacitors). They work fine until you put them under load and then start tweaking the voltage. Rafal spent a long time trying to get them stable (see the git history for longhaul.c). Given those CPUs are pretty underpowered today, and there are many better alternatives if you care about power saving that much, I'd vote for not worrying about it too much. We even stopped building it in Fedora due to a) the limited userbase and b) when we got bug reports there was nothing we could really do, so we opted for stability over power saving.
