A couple of things caught me out on a recent kernel build that may or
may not be relevant to you.
If you are building the kernel the "Debian way" using make-kpkg, you now
have to take the additional step of:
update-initramfs -c -k 22.214.171.124
after installing the kernel deb.
Check that you have an initrd line in your grub menu.lst entry and that
it points to something sensible.
I also discovered that it helps to have the appropriate modules for the
disc drives compiled in! Yes really!
WRT to new config options I accepted the defaults which seems to work fine.
