Two of my Linux machines use the Intel Ethernet controller on the
motherboard. These are both SMP machines. I have never, ever, had
any problems with the eepro100 driver that handles these chips.
I spite of the fact that the driver loops in the ISR, and does other
things that show poor design, it works so I have not done anything
to it. "If it ain't broke, don't fix it..."
So, if you have problems with using on-board Intel chip, it's
unlikely that it's a driver problem. If you have cards on the PCI
bus, the driver doesn't "know" any difference (PCI is PCI even if
it's not in a connector). You may find that the problem is caused
by PCI (mis)configuration since recent kernels use internal PCI
code. You may find that some bus master device does not have its
latency set correctly so it's taking over the bus. This can cause
problems with any high-activity device on the bus, such as a
network device.
