A terrible description of this bug is included below.

I have successfully narrowed the revisions that could have introduced this 
bug. I managed to build a 1.889.289.3 bk revision kernel. This appears to be 
the minimum revision which fixes the build bug I experienced in 2.5.64. The 
bug exists in this kernel, meaning that the bug was introduces somewhere 
between the 2.5.63 (1.889.1.133 bk revision) kernel and the 1.889.289.3 bk 
revision kernel. These revisions cover about 1 week of time. I am trying to 
build some in between revisions to see if I can narrow even more. Does anyone 
know of any craziness that went in between 2.5.63 and 2.5.64 that would have 
broken the way my computer reads these keys?

Thanks, Warren Turkal
