[Feisty] Today's updates (2.6.20-10) killed my nic

[NoOp]

Todays updates on Feisty Herd5 caused my ethernet nic card to stop
working. The card (Winbond Electronics Corp W89C940) had been working
just fine prior to the updates today. It shows up in lspci and the
Networking gui (it's configured with a fixed IP address), but lsconfig
shows:

eth0      Link encap:Ethernet  HWaddr 00:20:78:14:53:AE
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:9 errors:0 dropped:0 overruns:0 frame:0
          TX packets:45 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:2599 (2.5 KiB)  TX bytes:2808 (2.7 KiB)
          Interrupt:9 Base address:0xe400

I also tried setting it with DHCP and that changed nothing.

Updates went from kernel 2.6.20-9-generic to 2.6.20-10-generic.

Connected a Airlink 101 USB ethernet adapter that I use for testing and
that was immediately recognized and is up and running on eth1 without
any configuration necessary.

Backing down to 2.6.20-9 doesn't seem to make any difference, so it
appears that it might be something other than the kernel update that
broke it.

The card works just fine when running Dapper on the same machine.

Anyone else having networking problems after todays 2.6.20-10 update?
