Loren,
I'm always happy to see Mono.Posix get new functionality. It's a fun little assembly... Anyway, I have a few comments (merely from the point of view of a fellow Mono.Posix.Syscall hacker):
Most of the functions in Syscall are named after the equivalent library function. I'd suggest changing your passwd function to "getpwnam." Also, your function is accidentally private.
Stylistically, I'd also change the Account field of the Passwd structure to "Name," which seems more natural to me. (Also, HomeDirectory could just be "Home.") This is a picky point, I know...
I didn't know much about these functions before looking them up, but it appears there is a getpwuid function, which is the same as getpwnam function but looks up a user by uid. It'd be great if you added that to Syscall also, since it would only take a few more lines of code. You can reuse the same C function (like I did for stat and lstat).
Lastly, in your C implementation, rather than using getpwent_r and looping through the results for the right one, it'd be more concise to use getpwnam_r and getpwuid_r. (Again, I had no idea these functions even existed until just a few minutes ago. :) )
Anywho, cool.
