I tried everything, but apic is simply not turned on. My notebook (and
any of its components) is not listed in dmi_scan

At the bootup kernel just says: 
No local APIC present or hardware disabled

I tired everything.. i have "Local APIC suport on uniprocessors"
compiled into the kernel allright and "IO-APIC support on uniprocessors"
also. I 've read it could also conflict powermanagment so i turned ACPI
off and on, it didn't help. Should i try to turn APM on? I am compiling
my own kernels, not using debian sources. 
Any other idea how to tell kernel to use APIC? On what could it depend,
is there some special kernel bootup option for turning it on ?  
Everything worked fine on 2.4 kernel ...

Hmm now i got oprofile to say "oprofile: using NMI timer interrupt.",
but still no counters.
