John: 

Thank you, i will redirect my query to the appropriate mailing list.

Perhaps i should have explained that the em(4) driver in 4.x does
include support for the Intel 82573 1000/PRO nic; while the one in 5.x
does not. =(

Is it planned to merge the work on 4.x to 5.x and HEAD? 
i tried to recompile the kernel with the 4.x sources for the em(4)
driver, but obviously a lot has changed in the kernel, and as luck
would have it, my attempt did not yield any success.

Who would be the person to contact regarding this driver?

Thank you!

Hi,
           The driver in RELENG_4 is essentially the same as in HEAD 
and RELENG_6.  Someone backported the changes from the RELENG_6 
version to 5.x and posted a link in the mailling list perhaps a month 
or so ago.  Have a look through the archives for the 
patches.  However, I would suggest you go to RELENG_6 from 5.x.  6.x 
is a bit faster on a number of counts and quite stable on the boxes 
we have it running on.

Do i need to do something special with gstripe when upgrading to 
RELENG_6 from RELENG_5?

Hmm, you can try asking on stable@ or current@ perhaps.  I'm not sure who
the
correct person to talk to about em(4) is these days.  I believe it is 
ackerman@FreeBSD.org.

Support seems to be in HEAD and therefore 6.x already.  It looks like 5
has simply been missed.  I suspect all that is needed in the 5 branch
are the following changes, though that is untested:

http://lists.freebsd.org/pipermail/cvs-all/2005-May/121728.html

I actually have one of the affected cards which I was planning to use in
a 5-STABLE machine in the (semi-)near future, thanks for pointing out
the issue!

I think the version in 7 and 6 relies on other changes in the 
tree.   Have a look at

http://lists.freebsd.org/pipermail/freebsd-stable/2005-July/017292.html
http://people.freebsd.org/~delphij/MFC-RELENG_5/patch-em

that takes into account those changes.

Everything went fine even without reboot after make installkernel.
