[CentOS] display resolution

hi.
i got old acer veriton 3600g with intel 82865g graphics and should be able
to display at least 1024x768.

i'm linux newbie and this is my first hands on centos and it's centos 5.1.
why is it i can only use 800x600 resolution?
i tried install other distro and also few livecd and most distro can give me
1024x768
anyway i can get more screen on centos5.1?

tia.
