inigo@crono:~$ cat /boot/config-2.6.18-5-686 | grep CONFIG_NR_CPUS
CONFIG_NR_CPUS=8
This was the "vanilla" config also.
If you want more CPUs, you will need to compile.

P.D. be careful with top, if you press '1', on a 25 lines term, with 16
cpus, you only will see the headers, and not process information :-)
P.D.2 on top, if you press 'f', then 'j', then 'enter' you will see a
new column titled 'P', where you will see the CPU that is using each
process. Press 'W' to make it permanent.
