e1000, 2.6.1[34] - WOL not working

[Martin Volf]

Hello,

with 2.6.13 and 2.6.14, after I shutdown the computer I can't wake it up with 
the "MagicPacket" over the network. With 2.6.12 and 2.6.12.x it is working.

Steps to reproduce:
Boot 2.6.14, "ethtool -s eth0 wol g", press the power button, acpid runs 
"/sbin/init 0", the computer poweroffs, the link LED on the switch goes off 
and WOL is not working. With 2.6.12 the link remains on and WOL is working.

More mystery:
When I pull out the power cord for a while after the shutdown from 2.6.14, the 
link LED on the switch goes on and WOL is working. So it looks like 2.6.13 and 
.14 is in fact disabling the WOL.

Distribution: Gentoo

Hardware Environment:
CPU P4 with HT, MB Asus P4C800-E Deluxe (Intel 875P chipset) with onboard 
e1000 (Intel 82547EI) connected to a 10/100 switch

Software Environment:
latest BIOS
SMP kernel, more info: http://columbia.dragon.cz/~volf/wol_problem/
