downgrading this module to the version prior to this commit fixes the
issue.
The commit you mention does not touch dell-laptop.c. The commit before
that one doe, but it is only adding code. Digging the tree I found this
one between kernel v3.4 and v3.5-rc1:

dell-laptop: Remove rfkill code
The interface just doesn't work on some machines, and Dell haven't been
able to tell us either which machines those are or what we should be
doing instead. This would be fine, except it results in userspace ending
up confused and general sadness. So let's just rip it out for now.

You're right, I have no idea where I got that commit number from! Sorry
about that.
Actually, the behavior you describe and given you have a BCM4313 running
with brcmsmac I may point out that this driver has an issue coming up
with wireless disabled. This has been fixed in 3.7 kernel so you may
want to try:

brcmsmac: don't start device when RfKill is engaged
This patch fixes a bug when device is being started
while RfKill switch is engaged, leading to hang
due to partial initialization of hardware.

Maybe I should resubmit it to stable. Now there is an idea.
Yep that fixed it, thanks very much!
