[REQUEST] ASUSTek P5QL/EPU completely unlocked BIOS

[gepp0]

Hello!
I'm currently running the latest version of my ASUStek P5QL/EPU motherboard BIOS, v.0408, last dated 2009/09/28, still available at the following address: http://dlcdnet.asus.com/pub/ASUS/mb/sock...U-0408.zip
The BIOS works quite well, and seems to be fairly unlocked, yet since I started overclocking my Intel Q9400 CPU, I noticed it lacks some very important tweaks, such as complete controls over CPU Voltage (this is quite vital to optimize CPU temperature and avoid overheating).
Having done a little research, I found out more detailed options on the matter seems to be available on ASUStek P5QL-E and P5QL Pro motherboards, which should be very similar to mine (for details and screenshots, see: http://www.overclockersclub.com/reviews/...5qle/4.htm - screenshot n. 22/69 on that page).
My question is: would that be possible to unlock the curent BIOS version to allow CPU Voltage customization and all other tweaks that are not currently available on my model?
Many thanks to anyone who can provide a solution. I managed to push my CPU to a quite stable 3Ghz, but my temperatures reach 75° under stress, and I feel some voltage optimization should lower them a bit.
