I have a very recent laptop (Thinkpad X200s) and I noticed that Red Hat 
backports video drivers from newer Xorg versions to the one they ship.
So even if web-pages say you need at least version Y, it is possible that 
you can still make it work with version X.

You also have the possibility to make it work in VESA or framebuffer mode 
until the support is added in the future. For a list of things that are 
coming up in CentOS 5.3, see:

 	https://www.redhat.com/archives/rhelv5-announce/2008-October/msg00000.html

As an example all websites say that my very recent wireless card (IWL 
AGN5300) is only supported by kernel 2.6.26+, but in the upcoming CentOS 
5.3 it works on a 2.6.18-210.el5 or newer kernel thanks to the efforts of 
Red Hat.

My built-in camera requires the uvcvideo driver which is also part of 
2.6.24+, while Red Hat backported the driver to the 2.6.18-210.el5 
or newer kernel.

What I can say is that CentOS 5.3 (due in roughly 2 months) will have a 
lot of new driver support for recent hardware. And you can already test 
the upcoming kernels from:

Also, if you have Red Hat Network access, you can download the RHEL 5.3 
Beta Xorg drivers to test your hardware.

You can see my experience installing CentOS 5 on this laptop from the 
following wiki page:

BTW What video chipset do you have exactly ?

Good luck,
