Yeah, the current qemu -git was broken by this commit:

9dfd7c7a00dd700de36ca58005a7cb3934a62efb is first bad commit
commit 9dfd7c7a00dd700de36ca58005a7cb3934a62efb

    switch -drive to QemuOpts.
    
    Demo QemuOpts in action ;)
    
    Implementing a alternative way to specify the filename should be
    just a few lines of code now once we decided how the cmd line syntax
    should look like.

I found this out by attempting to install a Fedora 11 image this morning, 
with:

  qemu -m 512 -hda fedora-11.img -cdrom Fedora-11-i686-Live.iso -boot d

Current qemu can't do that.  The one before the above commit could.
