"extmod"   = For the "bit" map fonts. RECOMMENDED that it's included
"type1"    = Type 1 font rasteriser, your simple fonts. RECOMMENDED

"freetype" = support for True Type (ttf, ttc), Type1 (pfa, pfb), CID
            (cid), CFF, Open Type, bitmap (bdf, pcf, snf), Windows
            (fnt), PFR, and Type42 fonts. RECOMMENDED

"v4l"      = is  an  Xorg  driver  for video4linux cards.
  Do you have a TV card that you use with X?
  {even then for most of them it not required and just gets in the way.}

  Or do you like to look at your TV-card as if it was a "scanner"?
  (while some of them even work somewhat this way, I never saw any use.)
   

"glx"      =  This module requires other libs and configuration settings
              to function. And may even CRASH a display, if not properly
              configured.

"dri"      =  Another part of the 3D support.

To properly load "glx" and "dri" requires another section which is/was
listed below and a supporting kernel module that is loadable.
  (ie "nvidia-glx" )

"dbe"      = Double Buffer "Visual"/"Extention"
             Do you really require this? 
             IOW have a application that needs it

 It has had a number of BUGS and buffer overflow problems in the past.
 See: <http://xforce.iss.net/xforce/xfdb/31376>
 Or:
<http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=464>

Description:
   X.Org and XFree86 X server could allow a local attacker to execute
   arbitrary code on the system with elevated privileges, caused by an
   integer overflow in the ProcDbeGetVisualInfo() function in the DBE
   extension. A local attacker with privileges to send commands to the X
   Server could exploit this vulnerability using a specially-crafted X
   protocol request to corrupt memory and execute arbitrary code on the
   system with the privileges of the X server.

Not as bad as some of the similar features in "MicroSoft" code, but
close.


BTW
 Chuck the video driver you are/where loading is "intel" see:

 A simple Google on: xorg intel 945 GM
will yield a 55,000 hits are so.
 If you add your "distribution name" you should find plenty of
configuration information and/or howto set it up type info.
