Ok I understand. However, I am still unable to load the AU in Logic. This time I started with the Snow Leopard project and made the changes as described by the technical note. The project was unable to build until I removed AUResources.r from the "Build Carbon Resources" build phase (I copied the error I was getting below). Once again, the AU passed auval with no issues, I was able to load and use the AU in AULab but not in Logic.
Besides the changes that the technical note described, were there any other changes you had to make to the Snow Leopard project?
Sample code would be much appreciated.

I suspect you're using the Lion version of the sample code. I had the same problem. Logic isn't yet using the new AudioCompnents dictionary in in the Info.plist file, but AU Lab is (see Technical Note TN2276). The Leopard version of the sample code uses this entry:
#define NAME "SAMPLE: MyGreatAUEffectWithCocoaUI"
in the MyGreatAUEffectWithCocoaUI.r resource file. Logic splits this string SAMPLE: MyGreatAUEffectWithCocoaUI in half as [Manufacturer] : [AudioUnitName]. In other words, anything before the colon is the manufacturer and after the colon is the audio unit name.
In the end, I copied the Leopard version (which uses the MyGreatAUEffectWithCocoaUI.r file), and made the changes in Technical Note TN2276, including the new AudioComponents entry in the Info.plist file (which Logic SHOULD be using).
If you're still stuck I can probably upload a working version for you somewhere. I have to say I wasn't very impressed that the sample code is in such a mess; it makes it very hard for new audio unit/core audio developers to get started.

The plugin does not show up in the AU Manager. It did pass auval, and the format is 2 channel floating LPCM according to auval. FYI, I made the plugin by customizing the MyGreatAUEffectWithCocoaUI project that Apple provides. The weird thing is that I have the same problem when building that project unmodified. Is anyone able to see the MyGreatAUEffectWithCocoaUI audio unit in Logic without modifying Apple's Xcode project?

However Logic doesn't see it. I'm compiling the AU as 64 bit and opening Logic in 64 bit mode as well. I dragged the component file into Library/Audio/Plug-Ins/Components. Is there a reason that AULab can see the AU but not Logic?
Check Logic's AU manager (found in the preferences menu) - does your plug-in show up there? Is it enabled? Did it pass the auval?
