The signature sections are identical. Triple-checked that I was
comparing with the ext3.ko from the initrd that booted the system.
[...]
To make it even more interesting:
# cd /lib/modules/2.6.23-0.104.rc3.vsc.fc8/kernel/drivers/net/e1000
# insmod e1000.ko
Modules signature verification failed
insmod: error inserting 'e1000.ko': -1 Key was rejected by service
# strip -g e1000.ko
# insmod e1000.ko
# lsmod |grep e1000
e1000 125977 0
Ok. This makes me think that the signature generation and/or verification
are looking at something they shouldn't be. i.e., something strip changed.

Sure, I'll add that too.
Also hack modsign.sh to pass -v to mod-extract. The logs from mod-extract
for a given module and the printks from verification looking at that module
should give us something to go on.
