Dual Xeon, MTRR problem still there?

Hi,
  While my friendly dual Xeon machine now appears to be pretty fast, I
notice that the NMI counter is still incrementing like topsy; this
presumably means that there is still something dodgy going on.
A hdparm -t seems to be giving respectable values, so I am not quite sure
where the time/performance is going:

/proc/mtrr shows the following

reg00: base=0xf9f00000 (3999MB), size= 1MB: uncachable, count=1
reg01: base=0xfa000000 (4000MB), size= 32MB: uncachable, count=1
reg02: base=0xfc000000 (4032MB), size= 64MB: uncachable, count=1
reg03: base=0x00000000 ( 0MB), size=4096MB: write-back, count=1
reg04: base=0x100000000 (4096MB), size= 64MB: write-back, count=1
reg05: base=0x104000000 (4160MB), size= 32MB: write-back, count=1
reg06: base=0x106000000 (4192MB), size= 1MB: write-back, count=1

Here are two /proc/interrupts straight after each other:

           CPU0 CPU1
  0: 14047275 17655700 IO-APIC-edge timer
  1: 73 37 IO-APIC-edge keyboard
  2: 0 0 XT-PIC cascade
  9: 0 0 IO-APIC-edge acpi
 12: 1196 928 IO-APIC-edge PS/2 Mouse

Thats 2.4.0-test10 with last weeks patch.
