Laptop Laziness

I installed CentOS on my laptop months ago, but never completed the wireless setup because it required me to be tied to my desk where my wired network connection is. I've gotten so used to being able to plop down on the sofa or bed or wherever, that I didn't want to be confined to the desk. I finally started working on it today, but now I'm tired. Its going to take more time because my laptop used Broadcom driver BCM4312. There's an official driver now, but I need to compile it, and before I can do that, I need to make sure that kernel headers and development packages are installed. I updated my kernel, but I also need to update grub so that I can actually boot to the new kernel. CentOS isn't my primary OS so I have to do that elsewhere. I'm a ways from being able to compile the Broadcom driver so it's just going to have to wait some more.
