So far I've got the kernel compiled and ready for testing. xtascox has the image at the moment, but if anyone is interested in testing you're more than welcome to. All you need is a working Arch install. What you need to do, is to install this over your current kernel, and see if it still boots, so anybody with an Arch install in a Virtual Machine can do this, just make a snapshot first, as I'm pretty sure I've missed something.
Contact me for the download.
I have a temporary arch install on an external hard drive I was just messing around with. Seems like I could put it to more practical use by helping you
