I managed to edit the bios version 0407 myself (using
AMIBCP) and instead of selecting CPU FSB/VTT/etc, in my version all you have to do is select the overclock percentage you want.
My processor is a Q8400 (2.66ghz stock) and I am currently running it 10% overclocked (2.93ghz) using stock cooler.
By the way, it wasn't needed "some reboots" to enable the overclock option, but just ONE.
This is how I did here:
1) Flashed the bios using ASUS EZ Flash and it automatically rebooted after 5 seconds done;
2) Pressed Del, entered the bios, loaded setup defaults, gone back to "Advanced" tab, and the overclock option was there waiting for me;
3) Selected overclock percentage (10%) saved settings and rebooted;
4) Done, I was already overclocked to the percentage I choosed!

I download the bios file (so I could see what was edited) on the other topic you suggested me and I also read your response:

I own a Q6600 which has a 2.4ghz stock speed and I was able to get it to 3.1ghz by setting the FSB to 344, setting CPU VTT to 1.3v (not sure if that was really necessary) and setting +150mv CPU over voltage which allowed me to pass stress tests with no errors. I was hoping I could get it to 3.5 but it's good enough so far.
You should try this 0407 edited by me, I believe it will make possible you achieve 3.5ghz =)
If you do, please post results.
