I wish I could help. For now, all I can do it test. I wanna thank you for your work on the kernel, thanks to you I have my system completely ready for Lion once the kernel has been fixed. Being able to boot in at least gave me the chance to get graphics, network, sound and sleep situated for the time being.

As soon as you're done with the kernel, my system will be 100% ready for it! Please let me know if you need help testing as you continue developing the kernel.

***EDIT*** Thought it might be helpful to add that my system is working perfectly with this kernel aside from the xpchelper issue, as well as losing copy/paste function after about ten mins. I also have issues making changes to certain prefpanes, networking being one of them. I'm wondering if it all has something to do with having to run the 32bit DP2 Finder. Perhaps xpchelper doesn't like that and that's why it keeps crashing out on us? No idea if that's even relevant, just my two cents.
