[Cooker] 4 MB video RAM pathetic

[guran]

Hi
 
My card has 32 MB video RAM and is capable to furnish 1900x1200.

My monitor can handle 1600x1200 at 75 Hz.

Configuration -> KDE ->  Information -> X-server says 4 MB

In RedHat the Installer asks about the amount of video RAM and I can have  
1600x1200 and 1280x1024 at 32 bit.

In Mdk 8.1 I am only allowed 1024x768 at 24 bit.

There is no XF86Setup and Xconfigurator is a link to XFdrake.

How do you achieve higher settings?

regards
guran
