Linksys WRT54GL

I’ve ordered a new Linksys WRT54GL router for my SOHO to replace a Draytek 2600We, and I’m already looking forward to installing one of the available Linux distros onto it. The question is going to be: which one? (OpenWRT, SveaSoft, HyperWRT, DD-WRT, …)

In any case, I’ll be wanting OpenVPN on the beast. Suggestions?
