I disagree, we should not break the current e1000 driver in the kernel while 
there is a new driver coming up that introduces ich9 support without breaking 
(the old e1000) support for all other devices. This is why we want to drop a new 
version of the e1000 driver upstream instead, and put all newer devices in that 
driver.

For distro's not following kernel.org releases we have the perfect solution: A 
fully tested 7.5.5 driver on sourceforge that was extensively tested against 
RHEL5 for instance, but also a lot of other older kernels.

I sure hope to get it out before 2.6.23 merge window close... But anything can 
unfortunately happen.
