I unplugged it and plugged it back in a couple of times.  Absolutely NO led 
activity in the connector was observed, but since this board has 2 ethernet 
ports, the other port lit up like the 4th of July when I stuck the cable 
into it.  So I rebooted, and enabled that port in the bios, then booted 2.6.28, 
copied /etc/sysconfig/network-scripts/ifcfg-eth0 to ifcfg-eth1, edited it to 
call itself eth1 without even changing the mac address, did a 
'service network restart' which reported a failure downing eth0, then another 
upping it, and success upping eth1.  Pinged yahoo, works.

I will call my friend at the shop where I bought all this and see if he can 
arrange a preship of another board since ASUS has a years warranty.  But to 
me, its pretty fishy that it was working normally when I shut down 2.6.28, 
failed on the boot to 2.6.29-rc1, twice, and was still dead when 2.6.28
was rebooted.  That points an awfully straight and strong finger at 2.6.29-rc1.

>No fishy things in the syslog...

As you can see in the dmesg I attached, I had problems from the gitgo.
But just for grins, I'll check messages too, for the first boot, hang on a sec.

First was the usual your bios is crap, fixing it notice, then:

Now the above claims I am 'tainted' but I am not.

But it was up for about 4 minutes and from the log, I had a network, ntpd reported
sync status as good:

Jan 11 14:15:44 coyote smartd[3089]: smartd has fork()ed into background mode. New PID=3089.
Jan 11 14:19:32 coyote ntpd[2500]: synchronized to 204.9.136.253, stratum 2
Jan 11 14:19:32 coyote ntpd[2500]: kernel time sync status change 0001
Jan 11 14:19:38 coyote shutdown[3256]: shutting down for system reboot

So the first boot worked!  Long enough for ntpd, but once logged in, I had no 
network, and the leds on the port were dark.  Hence the 2nd reboot.

Then the next one, again to 2.6.29-rc1 had another Oops:

And again it claims I'm tainted.  There are no proprietary drivers in use
that I'm aware of.

Then, just about 10 lines later:
Jan 11 14:20:57 coyote kernel: [   22.214383] eth0: no link during initialization.
Jan 11 14:20:57 coyote kernel: [   23.784997] eth0: link up.

But it wasn't. ifconfig said it was, but no pings worked.  So I fixed the 
ifcfg-eth1 script to run, rebooted, enabling the other port in the bios as I 
did so, and here I am.  The one thing I haven't done is a full powerdown, 
which is next.

And I have now done that full powerdown reset, but the eth0 port is still dark
and powerless.

And this is all that showed up in dmesg's output when I moved the cable back
for a few seconds:

[  135.940984] eth1: link down.
[  145.266298] eth1: link up.

No note that a cable had been plugged into eth0. But it was.

This could be a 'co-inky dance', but my almost 60 years in electronics 
troubleshooting says there is a connection.

I sure won't reboot to 2.6.29-rc1 again until I have a replacement
motherboard sitting next to me, I don't want to wreck the last port
cuz I have no slots left to stick a nic in this one.

I surely do hope that's a syntax error.
