traceback from firstboot

Can you please run system-config-soundcard from console and attach the output?
and attach /root/scsconfig.conf (it can be genetared by system-config-soundcard,
in "System" tab")

No output on the console, but I will attach the resulting scsrun.log, which
contains basically the same traceback.

scsrun.log from failed run of system-config-soundcard

Okay, I traced it myself. This is crashing because the alsa playback device for
snd_powermac does not have info.vendor, nor do any of its parents.

Furthermore, getVendor() in soundcardHalBackend.py doesn't have a fallback for
this case. It just returns "None", causing a traceback.

I suspect we might need a workaround for snd_powermac - probably some fdi to add
info.vendor = "Apple Computer Inc" to snd_powermac devices - but getVendor()
should return something reasonable if it fails.

Per the hal spec
(http://people.redhat.com/davidz/hal-spec/hal-spec.html#device-properties-info),
info.vendor isn't a mandatory property to be present for devices.

For F-7, I've committed the very minimal handling of the fallthrough when the
vendor isn't found to at least avoid things crashing.  Post F7, this should be
reworked a bit more (so leaving open for that)

fixed in system-config-soundcard-2.0.6-6.fc6
