Compiled with DDK headers or w32api's ones?

Before making LpcPortObjectType static, which you and Filip show is 
actually wrong with respect to DDK headers, my first try was allocating 
the *OBJECT_TYPE calling

ExAllocatePoolWithTag(NonPagedPool,sizeof(OBJECT_TYPE),TAG_OBJECT_TYPE);

which should be fine.
