That shouldn't be necessary.  Just rmmod, and modprobe should pick up
the change.

/etc/sysctl.conf:
module.sbp2.parameters.serialize_io = 1

It's another way of doing it.  I am not sure if it will work, but it's
worth a shot.  No reboot necessary, just run sysctl, and rmmod and
modprobe again.  I am a little confused as to why the first way didn't
get it right - modules.conf is supposed to be honored by modprobe, and
if it's not, that's decidedly odd.
