I know that Verisign/Thawte and GoDaddy are both issuing certificates with  
the OCSP information. I am unsure about other CAs but support is picking  
up, and OCSP support is required by the current EV guidelines draft for  
certificates issued after 2010.

And roughly speaking we get at about one report a month about sites with  
revoked certificates that are still using the revoked certificate for some  
reason.

Such reports are so frequent that I posted an article titled "Is that  
website still in business?" <URL:

the error and how difficult it can be to get it fixed.
