After this is applied, I can no longer use http:/// URIs with the
curl driver, if I do not build with  '--enable-modules' passed to
configure.

  $  ~/usr/qemu-git/bin/qemu-system-x86_64 -cdrom http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/fedora/linux//releases/19/Fedora/x86_64/os/images/boot.iso
qemu-system-x86_64: -cdrom http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/fedora/linux//releases/19/Fedora/x86_64/os/images/boot.iso: Unknown protocol
qemu-system-x86_64: -cdrom http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/fedora/linux//releases/19/Fedora/x86_64/os/images/boot.iso: could not open disk image http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/fedora/linux//releases/19/Fedora/x86_64/os/images/boot.iso: No such file or directory


So it seems driver registration is broken in some way when modules aren't
enabled at compile time.
