Hmm, when I compare that to my /proc/cmdline, the short answer would be to remove the following options:
noapic nolapic apm=off noresume edd=off nohz=off hires=off processor.max_cstate=1 nomodeset
Now, if you are unsure wether or not you NEED one of these options, start the remove action with:
edd=off (Monitor modi detection stuff, uncritical on most systems)
hires=off (hires timer, uncritical on most systems)
noapic, nolapic (every modern (past 2003/2004) needs apic to controll interrupt handling, no apic = nosmp)
apm=off (system power management, only need for shitty BIOS)
nohz=off (AFAIK Intel speedstep / AMD Cool'n'Quiet need that removed)
processor.max_cstate=1 (removal of this should be uncritical in nearly all situations)
nomodeset (when you remove this, the kernel tries to use kms during startup)
Addenum: For a first blind try I would remove: "apm=off edd=off nohz=off hires=off processor.max_cstate=1"
That still does not give you SMP, but gives you a measure off security. If the system still works fine (other than no smp), you have a first win on your side.
For the second try remove additionally: "noapic nolapic"
This should give you SMP.
At last you can remove: "nomodeset noresume"
To get a near standard install.
I hope this give you a hint where to start.

Yamaban That was VERY helpful and informative! Thank you very, very much. I now have SMP again Felix, The reason you didn't find it under kernel or factory is this issue first showed up under a stock install and I asked in the main support lists...
