Never heard of ARK, but your assumption that changing the CPU or SIO
chip to a faster version will increase the data rate is incorrect.  The
data rate on a modem is fixed by the standard used.  In  other words a
1200 BPS modem will only run at 1200 BPS (unless it has other speed
options). The MNP protocols are similar in nature.  It may be possible
to upgrade to a more sophisticated protocol, but again, that has nothing to
do with the speed of the chips.
