For me it does but I did a little more than just editing the .config.

What I have done so far:
1. Enabled preempt using make menuconfig.
2. Flashed it.
3. Replaced as much modules as I can in the initfs with the new ones compiled with PREEMPT.
4. Switched on tablet. Tablet rebooted. Enabled no-lifeguard-reset with flasher. Now tablet stays on. Now I'm Pimpin.

Problem:
I'm trying to recompile the cx3110x **** with the Makefile tweaked to point to my PREEMPT kernel sources instead. Instead, a lot of symbols can't be found.

Here's my syslog for that:

If by somechance, I manage to fix those errors, think this will make a difference?:
