Should work.  The one caveat seems to be the auto-reset; it has to be disabled.  Folks have reported that a low-value resistor sometimes works.  When the resistor doesn't work, a capacitor has to be added.  There was a recent discussion in one of the Hardware sections.  Search there for details.

I'm kinda new to this and the forums and information I've found covering this tend to conflict. If I have an atmega168 without anything on it, and an arduino uno, can I use the uno to burn the bootloader to the atmega168? If so, how?
Sorry this might be a little less confusing, I bought an atmega168 from mouser, I'm assuming there is no bootloader already on it. I would like to be able to write to it (for example have it make an LED blink), is there a way to do that using the arduino uno?
Thanks

Yes.  The description is six posts above this one.

I ran the process multiply times, checking my connections and I got this error.

avrdude: Yikes!  Invalid device signature.
        Double check connections and try again, or use -F to override
        this check.

You've disabled the auto-reset and confirmed that the Arduino is, in fact, not resetting?
