When creating the SD card I failed to spot the optional step to resize the root partition. I wasn't entirely convinced by the steps on the wiki as it talks about deleting the swap partition and doesn't appear to recreate it. After a bit of browsing I used the following process.
Resizing the root partition
Firstly, to be able to run gparted (next step) you need to set the root password:
sudo passwd root
Next I moved the swap partition to the end of the SD card:
Launch gparted from within the GUI (under the Preferences menu), select the swap partition, Partition -> Resize/Move. It is possible to just drag the swap partition to the end of the SD card and apply the changes. After a system reboot there is plenty of empty space beyond the end of the root partition.
Now I can resize the root partition using the instructions in the wiki:
Here is my fdisk output before I made any changes:
sudo fdisk -cu /dev/mmcblk0
- p to see the current start of the main partition
- d, 2 to delete the main partition
- n, p, 2 to create a new primary partition
- w write the new partition table
sudo shutdown -r now
After the reboot you need to resize the actual partition. The resize2fs will resize your main partition to the new size from the changed partition table.
sudo resize2fs /dev/mmcblk0p2
Done! Here is my fdisk output after I made these changes:
Building Kernel Headers
With plenty of disk space available I was able to follow the instructions in my last post to build the kernel headers.sudo apt-get install git git clone --depth 1 https://github.com/raspberrypi/linux.git sudo mv linux /lib/modules/3.1.9+/build cd /lib/modules/3.1.9+/build make mrproper gzip -dc /proc/config.gz > .config make modules_prepare
Building ar5523 driver
With the kernel headers in place I as able to get further with the driver build.
However this still failed a little further on with a different error message.

Setting up SSH
I extracted the error message in the last step by enabling ssh so that I could use WinSCP to transfer the error log back to my Windows PC:
sudo service ssh start
