[avr-chat] at90can128 async crystal

Does the at90can128 require capacitors to ground on the
tosc{1,2} pins when using timer0 in asynchronous mode?
I've seen many atmega128 boards omit the capacitors when
using a 32.768kHz crystal. The at90can128 datasheet includes
them in figure 74; however, the atmega128 to at90can128
migration guide doesn't specify that capacitors will need
to be added. (And I can't find a similar figure in the
atmega128 datasheet to compare to.)

It's probably my code, but I want to officially rule out
the hardware. (My board doesn't include the capacitors.)
