I guess Im way behind on this, but what's the low-down on developing universal kexts, specifically nkes. I can't find any documentation on it specifically. I have read through most of the documentation for regular apps. Is there anything to keep in mind when working in the kernel?

Actually, not much is different between building universal apps and KEXTs with Xcode 2.2 (or xcodebuild from the command line). You really want to use Xcode 2.2 if you possibly can. Xcode 2.2 supports more per-architecture build settings that eliminates much of the grunt work like running lipo yourself.

One of the DTS samples, SampleFilterScheme <http://developer.apple.com/samplecode/SampleFilterScheme/SampleFilterScheme.html> was just updated to illustrate how to build a universal KEXT. The project uses the 10.4.0 Universal SDK and gcc 4 for the Intel architecture and the 10.2.8 SDK and gcc 3.3 for the PowerPC architecture. The sample's ReadMe outlines the project settings.
