- Update to 20080620 svn snapshot, which uses the new kqemu-kmod-devel

  port that now also works for the 32 bit "qemu" executable on amd64
  (if you build with the KQEMU knob on, you have to deinstall the old
  kqemu-kmod first if it is installed)
- Add an ALL_TARGETS knob that, if turned off, omits the remaining dyngen
  targets, eliminating the need for gcc 3.4 (everything but ppc and sh4
  has been converted to tcg in this snapshot)
- Add tcg fixes for amd64 guests on i386 hosts (two of three have been
  committed to qemu svn in the meantime) [1]
- Update the pkg-message about kqemu on amd64, and add a note about using
  nfs with slirp, the latter [2]
- Homepage now at http://bellard.org/qemu/ - update links
