This is still a problem in yum 3.1.6, but I notice fixed in CVS.

Here's the problem:

...
         self.conf.uid = os.geteuid()
->        if self.conf.uid != 0:
->           self.conf.cache = 1
...

After commenting out that code, and making the following changes to 
yumdownloader, I find that latest releases do indeed do a *much* better 
job at resolving dependencies.
