looks a bit different here, still irq 10, but I could successfully
load the modules for it:

| 00:0e.0 Ethernet controller: Digium, Inc. Device 8005 (rev 11)
|        Subsystem: Digium, Inc. Device 8005
|        Flags: bus master, medium devsel, latency 64, IRQ 10
|        I/O ports at e500 [size=256]
|        Memory at a0004400 (32-bit, non-prefetchable) [size=1K]

|        Capabilities: [c0] Power Management version 2
|        Kernel driver in use: wctdm24xxp
|        Kernel modules: wctdm24xxp

and it receives interrupts here:

this is a 5501-70 with 1.33c, running:
