As far as I can tell the only problems with a saturated cannister apart
from the environmental ones is that an EFI car may run a little rich
for a few minutes after start up.   Actually the cannister has a "purge
valve" that has been callibrated to open at a certain manifold vacuum 
this pressure is achieved only at certain revs.  So the running problems are
likely to be a rich mix for approx 30 seconds some time after start-up 
once you exceed the required revs.  Not a big problem for your engine,
the environment (as has been pointed out) is another matter :-)

Regards Scott.
