I have ThinkPad X60 with 82573L, and after upgrading to 11.04 beta with latest kernel it stop working almost at all.
Tested e1000e 1.2.20-k2 (in stock kernel) and 1.3.10a driver with no luck, booting with option "pcie_aspm=force" doesn't help, I've tried e1000e_recover.iso but it does not boot on my 32bit processor, and the last what strange I cannot read eeprom:

@tpx60:~# ifconfig eth0 up
@tpx60:~# ethtool -e eth0
Cannot get driver information: No such device
@tpx60:~# ifconfig eth0 down
@tpx60:~# ethtool -e eth0
