Yes, that's for programming the on-board micro.
You need the Jtag MkII to program another AVR via Jtag.

I know it comes with a 6-pin ISP cable, however look at the PCB. Right
next to the USB connector you'll see what looks like a JTAG port. I
expect it is only for programming the onboard micro, but I thought I'd
ask.

I have about 5 AVR ISP mkII programmers and all of them have 6-pin 
connector.
It is connected to ISP port  of mega128 (PD0, PD1, SPICLK, RST, GND, VCC).
No JTAG functions at all.
Alex. 

The mkII ISP cable has a 10-pin 100 mil (5x2) footprint that looks
suspiciously like an unpopulated JTAG header. Is this for programming
the on-board mega128 chip, or can it be used to connect to a target?

Thanks.
