pppoe in -current ppp - no matching session

I was hoping that things were gradually turning better with my
-current gateway machine which runs on an ASUS P4S8X (Sis).
I cannot go back to 4.8 because Soeren has got the ATA driver
fixed for this chipset. Otherwise I had to revrt back and swap hardware
to something more conservative.

One big showstopper is 
http://www.freebsd.org/cgi/query-pr.cgi?pr=51181 

The other thing is that my ppp (pppoe) sessions die notoriously. This
was way better if not to say 'simply not there' with 4.7:

/var/log/messages:

May  8 09:37:07 www kernel: no matching session
May  8 09:40:52 www kernel: no matching session
May  8 09:43:32 www kernel: no matching session
May  8 09:52:47 www last message repeated 11 times
May  8 09:56:47 www last message repeated 10 times

It seems to be in netgraph/ng_pppoe.c:

                                sendhook = pppoe_finduniq(node, utag);
                                if (sendhook == NULL) {
                                        printf("no matching session\n");
                                        LEAVE(ENETUNREACH);
                                }

When I visit the gateway machine the screen is full of these 
'no matching session' messages.

Also my machine doesn't do network connections through pppoe to the outside
any longer nor is it reachable from the outside world. Intolerable for a
gateway machine.

I'm frustrated with FreeBSD 5.0-current (and was already with FreeBSD 5.0-R).
