The X server is often a container for pixmaps from other applications.
If you run xrestop it could help to diagnose if it is truly the X server
or one of the applications on the system which is consuming the memory.

For instance here's some output (modified to fit the screen) of xrestop:

          Monitoring 33 clients. XErrors: 0
          Pixmaps:   52397K total, Other:     133K total, All:   52531K
total

Fnts Pxms Misc   Pxm mem  Other   Total   PID Identifier
1  177   34    29162K      6K  29169K   ?   Damn Small Lin1800000
1  13  113    10405K      5K  10411K   ?   [EMAIL PROTECTED]
0   0    0     4800K      0B   4800K   ?   <unknown>

In this case, 40MB on my XServer is being consumed by firefox and
gnome-terminal (The first two entries).

(xrestop is available in Fedora Core.  If you don't have it installed,
yum install xrestop should install it for you.)
