quoting menuconfig help:

If you say N here, the kernel will run on single and
multiprocessor
machines, but will use only one CPU of a multiprocessor machine.
If you say Y here, the kernel will run on many, but not
all, singleprocessor machines. On a singleprocessor machine, the
kernel will run faster if you say N
here.


So I'm more for offering both kernels. I don't know which systems are 
excluded by "many, but not all", but as long as we distribute an i486 iso 
instead of an i565 or  i686 one and especiall as long as we ship a 32bit one 
(the multicores being mostly x86_64), the primary target of this iso is a 
single core 32bit processor - starting at i486 and compatibles (perhaps 
emulated in a vm)...
I am used to other isos offering an smp kernel as additional choice. We could 
argue for the future if the smp or the non-smp kernel should be the default, 
but I really think we should have both.
Producing the two should really not be the problem. Set the few different 
config vars, build, run the scripts (initrd), and just include one entry more 
for isolinux prompt.

At last, smgl is about choice ...
