It's possible to use 3rd gen SINIT/RACM on 2nd gen platforms. In fact, the

gen platforms were also affected by the buffer overflow bug in old SINIT

That is not a public link however, you need to login with an account. I have successfully registered an account and logged in, but then I get an Access Denied message when opening the link.
