Actually, he turned out to be using an older version of my firmware linux 
build script (the one with the 2.6.13.2 kernel, from the website), and the 
problem he was seeing is that building on an x86-64 machine in 32 bit 
emulation mode gets confused.

Once he started building in 64 bit mode, he got past that, but then hit the 3 
level page tables leak from 2.6.13 shortly thereafter.  I sent him a new 
build script using 2.6.14 and still am waiting to hear back...

Thanks,

Rob
