- FreeLdr Part II (ntoskrnl is now relocated, removes 3GB compiler
flag). Note that there is a bug in LD which Filip and I are examining,
so do not try this yet.
- Fix Registry ObRef/ObDeref bug -- Hartmut
- Fix SID Capture Bug -- Thomas
- Use KPRCB pointer properly (results in more portable and much
faster code)
