Description of problem:
Trying to set a T41 with a Radeon Mobolity 7500 to use a Dell 2001FP
in analog mode.

Version-Release number of selected component (if applicable):
system-config-display-1.0.23-1

How reproducible:
Always

Steps to Reproduce:
1. Check 'Use dual head'
2. Select Monitor
3. Press 'OK'
  
Actual results:
Traceback (most recent call last):
  File "/usr/share/system-config-display/xConfigDialog.py", line 208,
in ok
    primaryPCIBus = "PCI:%d:%d:%d" % (self.state.get_videocard_PCIBus(),
TypeError: int argument required

If I press 'OK' again, I get:
Traceback (most recent call last):
  File "/usr/share/system-config-display/xConfigDialog.py", line 155,
in ok
    lower_vrefresh, upper_vrefresh = self.second_monitor_vrefresh
ValueError: too many values to unpack

Not sure if this should be two separate bugs or not.

Expected results:
dual-head is configured.
