Ralink RT5390 Does Not Work on the UEK Kernel

Question

We installed OL6.3 and Ubuntu 12.04 on a new Asus X45A notebook. It has a Ralink RT5390 wireless card. With Ubuntu, both wifi and video work flawlessly. However, the wifi driver (from elrepo) does not work for the the uek kernel (2.6.39). While the wifi driver works when boot into the RHEL kernel (2.6.32), it created an "even bigger problem" in that the video starts at about 1/10 from the left edge of the screen.
As a result, we can only boot into Ubuntu on this new notebook, but we would like to use the uek kernel. Any suggestion will be appreciated.

It wouldn't surprise me if was more power efficient because half your hardware, e.g. wireless apparently isn't working ;-) I have three notebooks running OL6. Wireless works on all three of them. (One of the notebooks its wireless has problem with the UEK kernel, but no problem with the RHEL kernel.)
However, power management support means computer sleep and idle functions to slow down your computer's power
consumption when it is not needed, e.g. down clock your CPU and slow down your hardware, dim your screen, etc.
when running on battery, etc.This needs further verification, but all these functions seem to be working with OL6.
But again, please no one be fooled by my overly optimistic and simplistic comments*. The reality is, I am glad OL6 desktop works at all.
* For example, I actually installed OL6 on 4 notebooks, one of them "does not work" because I couldn't dim the screen. I did not intend to lie, but subconsciously, I somewhat forgot that there was this failed case.
