Description of Problem:

I've an old server with a CL-GD5420 video card (512 KB video ram -
it's really old ...) (an onboard chip in a Compaq Proliant 1500 server). anaconda doesn't seem to find the card and therefore fails, leaving a nice traceback.
This happens in both GUI and TUI install modes.


#############################################################
GUI install:

Probing for video card:
Probing for mouse typ0e:

Traceback (innermost last):
File "/usr/lib/anaconda", line 397, in ?
   mousehw)
File "/usr/lib/anaconda/.xserver.py", lin 87 in startX
   probedServer = video.primaryCard().getXServer()
AttributeError: 'None' object has no attribute 'getXServer'




###########################################################
TUI install (after package selection):

Traceback (innermost last):
   File "/usr/lib/anaconda", line 561 in ?
      intf.run(id, dispatch)
   File "/usr/lib/anaconda/text.py", line 365 in run
      rc = apply(win, (self.screen, ) + args)
   File "/usr/lib/anaconda/textw/xconfig.text.py", line 506, in __call__
      self.xconfig.filterModesbyMemory()
   File "/usr/lib/anaconda/xf86config.py", line 742, in fiterModesByMemory
      self.modes = self.availableModes()
   File "/usr/lib/anaconda/xf86config.py", line 700, in availableModes
      vidRam = self.video.primaryCard().getVideoRam()
Attribute Error: 'None' object has no attribute 'getVideoRam'





How Reproducible:
100%

Steps to Reproduce:
1. get yourself some old video cards ... ;)


Actual Results:
installer crashes

Expected Results:
well, a server doesn't need a nice GUI. So why bother?
GUI installation should fall back to TUI installation.

Additional Information:
It's hard to write down those tracebacks if saving them doesn't work ... ;))
