[Asterisk-Users] OT: RHEL / CentOS Enable APIC

Hello!

I'm setting up Asterisk on a new system.  In the past, all of my Asterisk 
boxes have either been embedded-style systems that do not supoort APIC, or 
multi-processor systems where APIC comes along with SMP.  However, now I'm 
trying to install Asterisk on a single CPU (and non-HT) system that does 
support APIC (A P4 Northwood an Intel 845 chipset).

I've used both RHEL3 and RHEL4 (and CentOS 3 as part of Asterisk at Home). 
For the life of me, though, I cannot seem to get an APIC enabled kernel 
installed.  It seems that because it's a uniprocessor system, the default 
is to load a uniprocessor, non-APIC kernel.  On the 2.6 kernels I've tried 
adding "lapic" as a kernel parameter, but it does not help.  I must say 
that I'm surprised that Asterisk at Home doesn't do this automatically, given 
the benefits of an APIC-enabled kernel for Asterisk.

Is there a way with either RHEL or CentOS to force it to use an 
APIC-enabled kernel?  I've tried Googling but no success.

Thank you very much for your help!
