You know, this is a problem not just limited to SMP vs. uniprocessor.
The general problem is that, if you ever have multiple kernels of the
same version compiled with different parameters (or different patches)
booting on the same root partition at different times, one kernel will
probably end up trying to use the other kernel's modules sometimes,
which is sometimes bad. SMP vs. uniprocessor is just one instance of
this.
It would be nicer to provide a "configuration name" option which would
be interpolated into the modules directory name (or, perhaps, was the
modules directory name). I would name my configurations "2.0.0-basic",
"2.0.30-very-basic" and "2.0.30-PC-speaker". (The first two are just
in case something breaks in the third one.)
Kragen (hey, maybe I should be implementing this instead of complaining
about it -- ya think?)
