I'm running Google Earth right now on my F8 system.  I didn't have to do 
anything special.  The system is a Dell Inspiron 640m laptop with Intel 
graphics, and Google Earth 'Just Worked' with no extra drivers required.

On my desktop F8 system, the only difference is that I have an nVidia card (so 
that SecondLife will work; we are doing some educational development in SL); 
in order to get GoogleEarth to work, I installed the livna nvidia driver, and 
it just works.

The livna RPM of the nVidia driver IS THE NVIDIA DRIVER THAT NVIDIA 
DISTRIBUTES; it's just packaged properly for Fedora, and just works (at least 
on my hardware).  If you use the raw nVidia driver file you will have 
problems due to the GL library problem already mentioned; the nVidia raw 
driver simply doesn't respect the existing ownership of some files, and, 
since it was installed to allow the RPM database to know about that, the next 
time that portion of you system is updated the nVidia files will be 
overwritten (which will crash the nVidia driver).  And, if the nVidia 
installer doesn't register those overwritten files with the RPM database, 
just exactly how does RPM know to not overwrite when that portion is updated?  
This is nVidia's fault for not working with the installed system's package 
manager; it's not Fedora's fault.

The livna crew have made the nVidia distributed binary drivers 'Fedora-fied' 
(for lack of a better word) and the system then works correctly.

Again, the livna nVidia drivers ARE the nVidia written and distributed 
drivers, just with the packaging change to allow the nVidia driver to 
peacefully coexist with the rest of the system.

This is one reason that, if at all possible, I try to always use properly RPM 
packaged programs rather than try to build from source (there is one major 
exception to this rule for me, and that is Plone, since the Plone versioning 
is pretty critical, and upgrades aren't necessarily smooth; plus, Zope and 
Python 2.5 are not friends yet; in the Plone case I use the plone.org unified 
installer, which installs all needed dependencies in a separate tree).  If i 
install a package that overwrites an RPM-managed file, then I can EXPECT an 
upgrade to the package that, according to the RPM database, owns that file, 
to cause system breakage.  This  is basic system administration stuff.
