Once loaded, it seems to work perfectly.
Sorry for the long wait, there's some new information on this that just this morning arrived.
We received reports from SuSE that on a T60 they were seeing the same problem. After obtaining a T60 ourselves we managed to spot the suspected problem: it is related to the "smart power down" capability of the PHY. Lenovo had this feature turned on in certain BIOS'es which caused the EEPROM reads to fail.
Some people reported that the problem goes away when you plug in a cable - this guarantees that the PHY is turned on and probably masks the issue for a lot of people (either you work plugged in or forget about the NIC when you work wireless, thus not seeing the issue).
The latest EEPROM's from Lenovo (obtainable from their websites as .iso) seem to have this feature turned off, which resolves the issue.
We're right now working on seeing if we can find a workaround for the issue ourselves in the driver, but in any case you can always try to grab the latest BIOS from lenovo's website, and tell us if that works for you.
meanwhile we're working on a more permanent solution.
