With My Inspiron 1501, I'm also seeing this bug where the wireless is hardblocked. To complicate matters, I'm having a problem in that the keycode for the wireless button [Fn-F2] isn't mapped.
Code:
May 10 17:14:51 ubuntu-dell kernel: [  191.862248] kbd_keycode: 15 callbacks suppressed
May 10 17:14:51 ubuntu-dell kernel: [  191.862257] keyboard: can't emulate rawmode for keycode 240
May 10 17:14:51 ubuntu-dell kernel: [  191.862296] keyboard: can't emulate rawmode for keycode 240
Any suggestions?

Code:
lsmod | grep dell
If dell-laptop is loaded, remove it:
Code:
sudo rmmod -f dell-laptop
sudo rfkill unblock all
Is your wireless working now? If so, we'll need to blacklist dell-laptop.
