CentOS - Aug 2010 - Two display cards problem

My Thinkpad notebook has two the same display card. It is installed with
Windows XP system and CentOS 5.3.

When I reboot from CentOS to xp,   the display card driver of windows xp  is
broken.    I guess if the display card is switched in the CentOS?      How
to let these two system use the same display card?

No change is made in the display card by an OS that will affect how the card
works when you boot with another OS later. If XP doesn't work right, you
might need a better software driver for that card for XP. It has nothing to
do with CentOS.

if you power off, does it then work in XP ?   if so, I bet there's some 
mode settings on the video card that the BIOS reboot doesn't completely 
clear and the windows driver isn't expecting.
