I wrote up the wiki guide on this, but for the last six months I haven't been able to get it to work. If somebody does have it working please see if the guide needs updating - something seems to have changed. It is annoying because my system seems to freeze up on rare occasion and I'm sure there is a panic/etc on the console obscured by X11. At the moment, however, some kind of xorg freezeup seems to be what is driving me crazy (seems like a driver puts it into a loop and makes it freeze for 30s at a time, with even alt-sysrq-r not always working. Moving both kernel and xorg from stable to ~arch didn't help with that either... Ugh. Rich
