I posted a series of patches to do this last year:
It generated some discussion but AFAIK didn't go anywhere.

Henri, if you want a quick hack to add specific options to kvm, you
can just specify a script as the KVM binary and have it add or modify
arguments as you wish.  For example, I used:

  while [ $i -lt $# ] ; do
      # Use rtl8139 network card instead of default ne2k_pci
  exec /usr/bin/kvm ${ARGV[@]}
