The problem isn't with qemu.  MinGW doesn't support largefiles yet so qemu can 
internally handle this (for example, qcow), but the physical file cannot be 
larger than 2GB on MinGW.  Petition those guys to fix this.  Cygwin has 
supported largefiles for some time now, but I don't know what the holdup is 
on MinGW.
