Everything is fine with a eepro100 on the 64x2 box that gave the same problem with a nVidia Corporation MCP51 Ethernet Controller (rev a1) using the forcedeth module. On the x86_64 laptop the problem is with a Broadcom NetXtreme BCM5788 using the tg3 module. Switching back to a 2.6.18.2 kernel, there is no problem. With all configurations of cards on both, route -n is the same on all kernels and instantly reports back. With >=2.6.19 on the laptop, netstat -r takes a very long time before returning the information ~30 seconds, instantly on 2.6.18.2.
