is this supported for burning the arduino bootloader to an AVR yet?

If you download the USBtinyISP version of avrdude (USBtiny-based AVR Programmer), you can use it to burn the bootloader onto an Arduino or other AVR. The next version of the Arduino software will have a built-in menu item for burning the bootloader with a USBtinyISP.

awesome and after the bootloader is burnt with AVRdude you can use the arduino software?

Yes, I just built one and burned two atmega 8 and three atmega 168. It works like a charm and was easy to build.
