This sounds like an interrupt handling issue. I suppose the NIC ends up
sharing an interrupt with the VGA card, which is why things only go
south when you run X.

Can you somehow re-assign the IRQs so that VGA and NIC don't share?

I don't know how you'd do that in Linux. However, your BIOS might have
some options you can tweak...
