I can confirm that this bug exists in Dapper since version 2.6.15-26.47. The changelog states that skge was then updated to version in 2.6.17, to obtain fixes and D-Link DGE-530T support.
I was able to reproduce the bug on two identical computers (ASUS A8V Deluxe Mainboard, with a Marvell 88E8001 Gigabit Ethernet Controller onboard), attached to a Gigabit-Network.
I can also confirm that Alexander's Patch above fixes the issue with no ill effects so far.
