No. I've made numerous kernels with only "esp0..." on both Quadras.

maybe. :) Some of the options are "defopt'd", so for example, changing
ADB_DEBUG recompiles the right files even without a make depend. If you're

out.

Maybe. Scott Reynolds supplied a patch to the timing calculation that
seems to work for me. It's already in current. I'd like to think there's
going to be another patch against 1.4, or a 1.4.1, but I don't know.
