The ASUS UL20A is my laptop named 'Smallbook'.
Drivers
Synaptics Touchpad
Get the 16.2.21 drivers from their website at: http://drivers.synaptics.com/Synaptics_v16_2_21_C_XP32_Vista32_Win7-32_XP64_Vista64_Win7-64_Win8.zip
It appears that any drivers > 16 will fail to install on the laptop, under Windows 8.1. This version contains the two finger scroll built-in.
Issues
Linux
The module atl1c drives the onboard Atheros ethernet adapter but will use up all the available CPU. This happened on the Linux Kernel used by Ubuntu (3.13.0-24) while running ClonezillaAlt. Removing it is not an option since it will kill the networking.
You can verify this after booting into linux by running the following a few times.
echo l > /proc/sysrq-trigger
dmesg | tail -n 50
The kernel worker, kworker/x:y (where x and y are random based on which CPU core is running the module), will use up 100% of the available CPU of one core.
