[avr-chat] AVRs with JTAG and without centre pad?

While waiting for my ICE-Cube to arrive, I looked at datasheets
at Atmel's site. It seems that all the devices that have JTAG
come in surface mount packages that have a centre pad underneath
the package. Please tell me I missed some device ;-)

Otherwise, I guess I need to learn to deal with the centre pad.
I gather it is mainly a heat sink, so does placing some vias
under the component and soldering from the other side work?
My soldering skills are not really that extensive, so if anyone
has good AVR specific advice, I'd be grateful. I have already
perused the net for generic SMT soldering.
