Basically, yes. Unless you can get your hands on the relevant MOF, which is a good step in the right direction in at least spelling out what the methods are for, even if it doesn't tell you the right arguments to pass (for newer Acer laptops, it was dug out of the Windows binaries using 'string').

One way I've used in the past was to use the Windows Kernel Debugger to trace ACPI and replicate the function calls.

In some cases, you can also guess based on the naming conventions used in the DSDT, and/ or seeing how arguments are handled when the are passed in.
