We have a pair of X4100M2's in production right now running 6.2, though
we run a pretty cut-down kernel that lacks USB support.  There are some
dmesg warnings related to the IOAPICs but they seem harmless:

FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
cpu0 (BSP): APIC ID:  0
cpu1 (AP): APIC ID:  1
cpu2 (AP): APIC ID:  2
cpu3 (AP): APIC ID:  3

ioapic1: WARNING: intbase 48 != expected base 24
ioapic2: Changing APIC ID to 7
ioapic2: WARNING: intbase 56 != expected base 55
ioapic3: Changing APIC ID to 5
ioapic3: WARNING: intbase 24 != expected base 63
ioapic0 <Version 1.1> irqs 0-23 on motherboard
ioapic3 <Version 1.1> irqs 24-47 on motherboard
ioapic1 <Version 1.1> irqs 48-54 on motherboard
ioapic2 <Version 1.1> irqs 56-62 on motherboard

Disks work fine with mpt(4), just as with !M2.

2 nVidia nForce nve(4)'s and 2 Intel Pro/1000 em(4)'s.  Quite a step
back from the quad em(4)'s in !M2's, but 2 usable NIC's should be enough
for most uses.
