Yep, just did that. The last things printed right before hang are:
ioapic0: Assigning ISA IRQ 1 to local APIC 0
ioapic0: Assigning ISA IRQ 4 to local APIC 1
ioapic0: Assigning ISA IRQ 6 to local APIC 2
ioapic0: Assigning ISA IRQ 7 to local APIC 0
ioapic0: Assigning ISA IRQ 9 to local APIC 1
ioapic0: Assigning ISA IRQ 12 to local APIC 2
ioapic0: Assigning ISA IRQ 14 to local APIC 0
ioapic0: Assigning ISA PCI 16 to local APIC 1
ioapic0: Assigning ISA PCI 17 to local APIC 2
ioapic0: Assigning ISA PCI 18 to local APIC 0
ioapic0: Assigning ISA PCI 19 to local APIC 1
ioapic0: Assigning ISA PCI 22 to local APIC 2
trying to mount root from ufs:/dev/ad4s1a

Yes, that is pretty much it. The Realtek ethernet isn't working in in
7.0-RELEASE either, but I'm guessing that that is a different (and less
serious) problem related to changes in that device.

It looks like when I try a single-user mode (and verbose) boot the only
difference is that the las line shown above (the start_init line) isn't
printed. Otherwise, the hang is the same.

Ok, that'd be great. I must say that I'm close to simply returning this
MB and going with something not quite so new that is more likely to
work. I was hoping to get this system up and running this weekend. :(
