Thanks for clarifying that, I suspected it to be the case, but wanted
confirmation since it is a new company laptop :O

The first thing I did was to reboot in 2.6.25 and verify the ethernet -
it was fully functional via DHCP.

Also to me, the MAC address seems fine:
linux-7vph:/ # ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:1C:25:95:93:EC
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Memory:fc200000-fc220000

(Right now, I'm using iwlagn, not ethernet)

Well it loads fine now, but this is after I have switched back to 2.6.26.5.

Too scared to try 2.6.27 again, but I definitely saw a boot message in
an asterisk surrounded block that said something about NVRAM checksum(?)...

s2disk, not sure if there are other corruption "triggers".
