new kernel option

[520066587150-0001@t-online.de (Jerome BENOIT)]

Bonjour:

I have just tried to build an SMP kernel:
surprisingly some options can be seen in grey
(when `make xconfig' is used)
but they cannot be selected:
apparently the Makefile does a pre-choice.

How can we make all options available ?

Thanks in advance,
Jerome BENOIT
