I don't know much about kernel32/ntdll, but I'm pretty sure that you
could get this to work through ntdll. NtQuerySystemInformation with
SystemProcessorInformation/SystemLogicalProcessorInformation (see
http://undocumented.ntinternals.net/UserMode/Undocumented%20Functions/System...)
should help. http://native-nt-toolkit.googlecode.com/svn/trunk/ndk/extypes.h
(read, don't copy) seems to have a pretty exhaustive set of
definitions, but even that's not complete. Some tests for the NT
version would be useful.
