I have updated my Ubuntu kernel to 3.12 so I can take advantage of updated DPM.

I am trying to find firmware for my radeon from this website

http://people.freedesktop.org/~agd5f/radeon_ucode/

I did a lspci | grep VGA

and I get this

01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880M [Mobility Radeon HD 4225/4250]

Which firmware do I use so that I can add it to /lib/radeon

The ATI Mobility Radeon HD 4225/4250 is a RV610/630 chipset, so you will only need R600_rlc.bin. However, from what I can tell (based on the file modification times), Ubuntu 13.10 already includes the latest firmware for R610/R630.

I think you may only need to enable DPM from the kernel command line, since DPM is not enabled by default. Just boot with radeon.dpm=1.

If DPM is enabled, you should see something similar to the following in System Log:
