Just as a clarification, the module configs can be stored in the short form:
EXPERIMENTAL=y
MODULES=y
PCI=y

I checked, in my current kernel/modules nothing matches the above regexp,
and even if it did, having a garbage config value wouldn't be fatal.

This will work for the bzImage, but not the uncompressed kernel. If you
remove the "^" (start of line) requirement it works for both:
egrep '[0-9]+\.[0-9]\.+.*\(.*@.*\).*[0-9]+:[0-9]+:[0-9]+'
