[BUG] iwlwifi 3945 works only with disable_hw_scan=1

[Maxim Levitsky <maximlevitsky@gmail.com>]

I recently bought an acer aspire 5720G, and wireless didn't work with
standard ubuntu 2.6.24 kernel.

I found that specifying the above option 'fixes' the driver
but I also noticed that list of available access points shrinks
to just one (the connected) point.

Moreover there is a trouble in changing a access point, it just hangs.
the button that toggles wireless does work, but doesn't blink.

I then installed latest -git kernel (~ 2.6.26-rc4) and got this:

* I still have to use disable_hw_scan=1
* Wireless led works thanks to acer-wmi
* If I disable wireless with the button, I _can't_ re-enable it unless
  I reload the module.

* List of access points doesn't shrink, and I can switch between those points.


When I omit disable_hw_scan=1, I get errors about REPLY_SCAN_CMD
I will send detailed debug info later.
