Having the pins untaped will not damage the card or the mac - the mac
wil simply not boot until the pins are isolated. Pin taping or isolating by
any method is required for all mac models with adc type connection via the
agp slot - so some 2x agp G4 models also require it. Early Sawtooth and
Cubes did not have adc so the taping is unecessary as pins 3 and 11 have no
function on those models.
Isolation can also be done by cutting the traces to the pins or removing
the resistors which control them for a more permanent and less messy method.
I think nail varnish will also do the job - never come across it though....
