Patch has been applied when system rebooted the first time after
fresh install. File /etc/system has never been touched.
Original file layout:-


# mkdir /mnt/tmp
# mkdir /usr/lib/xen-solaris
# cd /usr/lib/xen-solaris/
# mount -o loop,ro snv76.iso /mnt/tmp
# cp /mnt/tmp/boot/amd64/x86.miniroot  /usr/lib/xen-solaris/x86.miniroot-76
# cp /mnt/tmp/boot/platform/i86xpv/kernel/amd64/unix  /usr/lib/xen-solaris/unix-76
# umount /mnt/tmp
