Also, I've seen problems with the Realteks in 2.6.9 kernels, that seemed to go away with later 2.6 kernels (around 2.6.13, from memory). Given the debian box is 2.6.8, that might be an issue, so you might want to try a later kernel. The forcedeth drivers on the ubuntu side are pretty recent (and so probably about as good as you'll get), but you could always try the nvidia nvnet driver for a comparison. Note that nvidia now recommend the forcedeth driver (recent kernels only) over the nvnet one, though. And what are you using to test this, incidentally?
