zImage.vmode was recently added. It's a version of zImage in which the ELF note section used by open firmware indicates that it requires a virtual mode instance of OF instead of real mode. This allows it to work with Apple OF, and thus is directly bootable (or netbootable) from OF command line. (Unfortunately, pSeries OF sort-of requires real mode and Apple OF sort-of requires virtual mode, and both tend to be unhappy if no notes section specifies the mode at all). However, we forgot to add zImage.vmode to the default G5 build. This fixes it.
