I use an ASUS M2NPV-VM board with an onboard nVidia nforce 430 NIC, and
an additional RTL 8169 PCI NIC by Netgear:
00:14.0 Ethernet controller: nVidia Corporation MCP51 Ethernet
Controller (rev a3) (vendor/device = 0x10de/0x0268)
04:08.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169
Gigabit Ethernet (rev 10) (vendor/device = 0x10ec/0x8169)
The same problems showed up when using a 3Com Fast EtherLink XL PCI NIC
in combination with the same board.

I don't know if it's possible to explicitly force the NICs to share IRQ.
What I do is disabling ACPI in dom0 (acpi=off kernel parameter) and
activating each onboard device in the BIOS setup. The other BIOS
settings like "PnP aware OS" don't matter.
