correct; this was during a fc2 update

yes the plan is to not ship the sourcecode package at all for fc3 but
release note how to get the sourcecode from the src.rpm

actually it is to differentiate local builds vs buildsystem builds;
mostly that is for my own sanity so that I know my own local builds and
know that they don't match exact CVS tags

EXTRAVERSION is strictly defined by Red Hat, in upstream it's designed
for free use for packagers ;)

the gain Athlon gave previously is, in 2.6 kernels, now a runtime option
not a compiletime option, so no need to have different kernels for
athlon anymore.

why bother ?

even in 2.6?
