Attached are 2 .config's - config.gz is my usual laptop config, and
config-minimal.gz is the stripped-down version I was using while bisecting.

The failure mode was *really* odd - I could start up
iptables once, and get *one* error message about being unable to initialize
table 'filter' - subsequent attempts would all fail further along:

[root@...ing-police ~]# /etc/init.d/iptables start
iptables: Applying firewall rules: 
iptables-restore v1.4.2: iptables-restore: unable to initialize table 'filter'

Error occurred at line: 3
Try `iptables-restore -h' or 'iptables-restore --help' for more information.
[root@...ing-police ~]# /etc/init.d/iptables start
iptables: Applying firewall rules: iptables-restore: line 110 failed

Yell if you want any instrumentation added, strace, etc - I still have all
the pieces needed to dig into it further...

I didn't capture the output of iwl3945 loading, because I was expecting that
to be some *other* issue - reverting the problematic commit fixed 3945 before
I had started digging further into it.
