various for pre-compiled kernels

["Greg Wiley" <greg@orthogony.com>]

1) I used dselect to request a new kernel version from
stable.  It has some obvious configuration differences
from the former version.  Is the kernel configuration
file used for the build also stored somewhere on my
machine?  I want to compile a slightly modified version
but maintain Potato compatibility.

2) Are the modules listed in /etc/modules distinguished
somehow between different kernel images? It doesn't
look like it but I wonder if there is some mechanism for
specifying modules to load based on the kernel image
booted.

Thanks,
