Should also mention that I'm using Sun's VirtualBox 3.1.4 (not
rpmfusion's OSE version) and that after completing the RC4 installation,
even after adding all graphical packages, running RC4 in graphical mode
doesn't work either ("telinit 5" ends up hanging, although I can regain
control with Ctrl-C). Same is true with Rawhide after updating from
RC4. Don't know if there's any connection between the failure of the
graphical install of RC4 and the failure of either RC4 or Rawhide to run
graphically.
