File.Exists (path) should return false when "path" isn't
readable. However, it also returns false when "path" doesn't
exist.

If speed doesn't count, you may try to read the file while
catching the exception:

bool IsReadable (path)
{
     try {
         File.OpenRead (fileName).Close ();
         return true;
     }
     catch (UnauthorizedAccessException) {
         return false;
     }
}

If both cases are inacceptable, then you have to use
Mono.Unix.access.
