Bug 77676

On a Dell Dimension 4500S, I disabled the Intel on-board video card and 
added an ATI Radeon 7500 (PCI). ddcprobe lists the Radeon, lspci shows both
cards.

redhat-config-xfree86 will not start, even if I tell it not to use the existing
configuration file, because rhpl.videocard.VideoCardInfo() returns the onboard
card (it only returns the first card in the list from kudzu):

>>> import rhpl.videocard
>>> videocard = rhpl.videocard.VideoCardInfo()
>>> print videocard
primary: 0
vidCards: [<rhpl.videocard.VideoCard instance at 0x81f878c>,
<rhpl.videocard.VideoCard instance at 0x82ce8cc>]
Primary Video Card Info:
device: None

'NOCLOCKPROBE': ''}

Kudzu output:

>>> import kudzu
>>> cards = kudzu.probe (kudzu.CLASS_VIDEO, kudzu.BUS_PCI | kudzu.BUS_SBUS,
kudzu.PROBE_ALL);
>>> print cards

rhpl needs to either return the add-on card if there is a disabled onboard card
or return all cards found so the frontend program can ask the user which to
configure.
