802.1x - Compatible with SHA256/KSP/v3 or v4 templates?

Question

I'm preparing to implement a new PKI (two-tier, 2012 R2) in our environment, and we are also implementing 802.1x (on wired, currently, with wireless to come). All clients in the enterprise are Windows 7.  I've been researching what is supported in relation
to certificate templates, hash algorithms, and cryptography providers.  Everything I've seen so far states that 802.1x only works with v2 templates, SHA-1 hashing. 
Has this changed at all in the past two years or so (latest documentation I could find on certificate template versions being compatible with 802.1x)?  Is any combination of SHA256, Key Storage Providers, and/or v3 or v4 certificate templates supported
with 802.1x authentication?

Answer 1

I have a supplemental question regarding the 2003 update (KB968730).  I have a Kace KBOX that we do patching/inventory of our servers with, and it tells me that all of our 2003 servers are patched with KB968730.  However, when looking at one of
the 2003 servers, I didn't see KB968730 in the updates list, nor in the registry.  After some research, it appears that the crypt32.dll file on the server now is already a newer version than the one in the KB968730 (it contains the version of crypt32.dll
from MS14-049 in August 2014).  I went ahead and installed KB968730 anyways on the server, and it now shows up in the updates list.  However, the crypt32.dll file was unaffected on the machine since it was already newer.
Upon reading the install log for KB968730, it seems that all the update did was add registry keys to say that the KB968730 was installed, but did not replace the crypt32.dll file, and no reboot was needed.
I believe this will be the case for all of my 2003 R2 servers.  With the actual payload of the KB968730 being the crypt32.dll (and wcrypt.dll for x64), and those files already being newer than on my servers than what is in the KB968730, would it just
be considered to be SHA2 supported...or would the presence of the reg keys that state the hotfix is installed be needed (sounds pointless to me)?
EDIT: Not to mention that the KB968730 update never specifically mentions 2003 R2, just 2003.  The install log shows failures during file version checks and other lines, so it really looks like it simply added the registry info for the hotfix and
that's all.
