working to decrease the diff between the configs I've generated a new 
config (attached) which has the same result.

stripping out comments and modules (since I can boot your kernel with no 
modules available to it) I come up with the following differences in the 
configs (< is my config )

my config is for 2.6.16 while yours is 2.6.15.5 so some of the differences 
are due to the version skew.
