IBM T41 + ACPI + APIC

Hi,

I have an IBM T41 with FC2.
I compiled a 2.6.8-rc3 kernel with ACPI and LAPIC support.
In dmesg I find:

......
Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!
......
ACPI: Using PIC for interrupt routing
ACPI: PCI Interrupt Link [LNKA] (IRQs 3 4 5 6 7 9 *10 11)
ACPI: PCI Interrupt Link [LNKB] (IRQs *3 4 5 6 7 9 10 11)
......

Is something wrong with my local APIC ? 
Why ACPI is still using PIC instead of LAPIC ?
No sign of LAPIC in /proc/interupts :

cat /proc/interrupts
