I am having the same latency problem with OpenSuSE 10.1 using the default kernel of 2.6.16.13-4-smp on the lenovo T60. I have tried loading the e1000-7.3.15.tar.gz package from intel with no change in outcome. I have also tried configuring a cisco vpn client using this interface with no success which is to be expected.
