This page lists all the exports that were added to the HAL for version 6.0, i.e., for Windows Vista. One is exported only from the x64 builds (until version 10.0 makes it also an x86 export). Another doesn’t survive even to the first service pack, i.e., Windows Vista SP1 which is also Windows Server 2008. Five do not start until Windows Vista SP1.
Although this version brings by far the largest increase in exported functionality since the HAL’s creation, not even one of the new functions is documented. One, merely shaded yellow below, is at least declared in a WDK header file (though with no indication of which Windows versions it appears in).
