Since disconnecting the network "solves" your problem, I'd agree with your assessment that the NIC is causing your lockups. While you could install a better NIC, it's probably a good idea to add some cooling to the system. Another fan (blowing out the back of the case) can't hurt. Note that 100BaseT uses a 120MHz clock (IIRC), which is faster than a i486 CPU.
PS. I had already added extra cooling when the lock-ups started; made no difference.
