You won't find a function in kernel/module.c that looks like it has the name "sys_init_module". Instead, the function is defined by using a macro, and it looks like this:
/* This is where the real work happens */ SYSCALL_DEFINE3(init_module, void __user *, umod, unsigned long, len, const char __user *, uargs) {
The use of SYSCALL_DEFINEx(func_name, args) is a fairly recent change (well, January, 2009) that may be the reason why you think that there has been a change. See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1a94bc34768e463a93cb3751819709ab0ea80a01
