The reason I was not getting interrupts on devices in the pci slot on the EPIA is because they were not set to be bus masters, so they would never generate interrupts. A quick write to the command register fixed the problem. Command register is being set to 0x02. It should be set to 0x06. a 6 to 4.
I haven't looked to see if this is pervasive throughout linuxbios, or if for other boards this is handled specifically, but it is a bug.
