Can I set the refresh rate without using official driver?
Currently I'm using powervr www.powervr.com based video card. It does have official driver for linux. But only support up to 2.4 kernel. How if I want to used 2.6 kernel? I don't need the 3d support. I just want to be able to set the monitor refresh rate.

THanks

You could use the 'vesa' driver instead. It is nearly universal. Then use the 'gtf' program to calculate the modelines.
usage: gtf <horizontal pixels> <vertical pixels> <refresh rate> -x

For example:

gtf 1024 786 60 -x
gtf 1280 1024 60 -x
gtf 1280 1024 72 -x

You will need to be careful about selecting the refresh rate. If you excede the rating of the monitor, you can damage it.
