[CentOS] Can't start X with latest CentOS 50. kernel

Nvidia driver for 6200 LE video card.

No problems with CentOS 4.5.  When installed (not upgraded) 5.0 X would 
not start.  X works fine with 2.6.18-8.1.3.el5 but only with xorg.conf 
as written for 4.5

Haven't seen traffic regarding this problem.  Has anyone else seen this?

Thanks,
Dick
