Because rNmp are used only for pointer params which have fixed size but
differs on different platforms. rNm are used for all non pointer
params and their size is unknown (can be byte/word/dword/qword/dqword)
but mostly don't differ on different platforms (or zero/sign extension
is needed).

OK. This is acceptable for me.
its generated code is identical to 05 version and
http://forum.doom9.org/showthread.php?p=1242697#post1242697 shows that
version 05 correctly works on Core2 / Phenom CPUs (both 32-bit and
64-bit Windows). Not tested is only Core i7 CPU and Linux 64-bit
platform. So if their tests is OK than I would think that the patch is
fully finished.
