SystemLogicalProcessorInformation seems to be the right SystemClass for 
NtQuerySystemInformation. But here's the Problem. I don't have any idea how i 
could any information about the struct returned by calling 
NtQuerySystemInformation with SystemLogicalProcessorInformation (= 73). 

The only windows machine i have access to a the moment keeps throwing status 
0xC0000005 (ACCESS_VIOLATION) at me which doesn't help at all and i'm pretty 
much stuck right now. If i could get my hands on the struct returned by 
NtQuerySystemInformation it should be easy to change the patch to do the 
parsing in ntdll and just call that from kernel32.
