It is not a Mac here, IBM Workstation. I can see the Processor as
Pentium 4 CPU 3. GHz (family 15, model 4). How to know EM64T enabled,
any command?

Trying to understand, should I set CPUSETS=y and SCHED_MC=y Or ignore them.

Yep, this ia a MacBookPro. I have decided about the distro. I did ask
this doubt when I got for the custom kernel compilation from source
after installation.

What I have seen in KConfig is, MPENTIUM4 used for the Xeon processor
too. I would try this soon on my Laptop (with SMP since it's a
Core2Duo). Anyway, shall post here.
