I'm attaching the lspci and dmesg output in case that helps. I am now less certain: I tried with a separate but similar machine, and eth3 still has bad interrupt test. I tried 2.6.9 kernel, same problem. I tried 2.4.29 kernel (on FC2 distribution), and the same problem exists. I tried with pci=noacpi, and this just messes up everything (irqs are disabled, etc). Could this be a bug in the motherboard implementation? Off to try some different combinations of NIC hardware...
