I also have the same issue. I, too, am using an ASUS motherboard with onboard intel graphics.
I decided to bypass using the 3.2... kernel. Instead I used Synaptic to apply the package: linux-generic-lts-quantal. This is currently bringing in the 3.5... version of the kernel. I Just applied latest kernel 3.5.0.28 and the problem seems to have been fixed. Here is the message from my dpkg log file after the maintenace was applied using the update manager: upgrade linux-image-generic-lts-quantal 3.5.0.27.34 3.5.0.28.35. So far no issues.
