Great! this solves quite some of the problems...
Nevertheless, looking at the changes I assume (I can't test it because I
use dynamic IP-addresses) that, if you start the connection using "real"
TCP/IP packets, they still will be lost because the packets will be
delayed until IPCP_UP is reached but as the interface is not yet running
(IFF_RUNNING is not set), the peer will probably ignore them??
I thing You still need something like /*!!!*/ to delay the transfer.

IF_DEQUEUE(&sp->pp_cpq, m);
if (m == NULL &&
((sppp_ncp_check(sp) && (sp->ipcp.flags & IPCP_UP))
|| sp->pp_mode == IFF_CISCO)) {
IF_DEQUEUE(&sp->pp_fastq, m);
if (m == NULL && ((ifp->if_flags & IFF_RUNNING) /*!!!*/
|| sp->pp_mode == IFF_CISCO)) /*!!!*/
IF_DEQUEUE (&sp->pp_if.if_snd, m);
}
