Hi Max,

I just tested it on the Ubuntu Hardy standard kernel on an AMD DualCore.
The /sys/devices/system/cpu/cpu1 entry doesn't show up.

I can send you the dmesg/config in private, if you want.

Did you test your suggestion? 

After our discussion, I tried to find the right spot to implement 
"disablecpus=" myself, but couldn't find the right position to hook it up.

If your idea would work out, I would ACK it. Even in bold :-)


Best Regards
