On irq 11, I also have
de0: <Digital 21140A Fast Ethernet> at device 18.0 on pci0
de0: interrupting at irq 11
and
the vga controller (as reported by BIOS mind you)
On irq 5, I also have
uhci0: interrupting at irq 5
Now, the behaviour is the same if I disable the USB or not. Again, the same
kernel config (minus the SMP stuff of course) runs just fine in UP mode.
Heck, here is the dmesg output with a kernel that showed the same symptoms, but
is two weeks older:

This motherboard is one of those where the mptable doesn't seem to be what we
expect:
bogus MP table, 3 IO APIC pins connected to the same PCI device or ISA/EISA
