Building the wl module on linux 3.2

After upgrading my netbook kernel to the latest stable version available on backports.org I soon discovered that my wireless interface no longer worked. Trying to rebuild the module resulted in the following error:

A bit of googling lead me to a few patches that helped solve the issue. Here is a unified diff of my changes which should allow you to cleanly build and install the wl module using module-assistant.

One thing to note is that the source code needs to be patched BEFORE you run m-a, i.e. cd to /usr/src/modules/broadcom_sta/amd64/src/wl/sys and run patch the patch from there.

I hope that somebody will find this useful.

Xbox 360 Repairs

I started playing Halo 3 at my friend's place and I got hooked so I decided I had to get a system for myself.

After doing some research I discovered that most of the 'broken' systems out there are easily repairable, all you need is 8 bolts and some washers, along with some Arctic Silver for the heat sinks.

I looked around Ebay I found a place that sells broken electronics which had a bunch of systems available, I sniped one and won it for a decent price. After I got the system the first thing I did was tear it apart and proceeded with the X-clamp removal process, put it back together and everything works, no more red ring of death!

While my repairs were successful I would only reccommend doing this if you're into electronics repair and have some experience working on circuits, you can easily screw things up if you don't know what's going on.
