On the kernel side, look for I_IXON in drivers/net/ppp_async.c. In pppd, the `crtscts' variable is set to -2 for xonxoff, and set_up_tty() in sys-linux.c then sets the IXON and IXOFF flags. If it isn't working, that's a bug and we should fix it. Running pppd under strace to check that it is actually setting IXON and IXOFF would be a start.
