You can use "make menuconfig" but the menu structure has changed
significantly:

make menuconfig
Device Drivers --->
   Networking support --->
     [*] PPP filtering

I currently run a 2.6.4 kernel and active-filtering works as expected
for it. I have also tried a 2.6.6 and found that active-filtering
does *NOT* work correctly for it. I configure and compile my own
kernels, with sources taken from kernel.org, so it's not related to
a particular distribution.

The problem doesn't seem to be the same as yours; there no message
such as you get. But the use of active-filtering stops all traffic
(inbound or outbound) from resetting the idle timer when an idle-off
time is set for pppd. I inquired about that on the linux-ppp mailing
list but there has been no response. In fact, I haven't received
anything from the list for several months.

"Stable" kernels are not supposed to be "on bleeding edge," but I've
experienced significant bleeding when using early versions of a new
stable series (and occasionally much later versions as well).

There's also another problem you have. I reviewed your first post and
found that the ISP requested PAP authentication and pppd rejects PAP:

Jun 26 18:43:30 localhost pppd[4188]: sent [LCP ConfRej id=0x1 <auth
pap>]

(Apparently I read just far enough to reply to your initial question and
no further.)

GPRS (cell) phone PPP services seem to do strange things, which is
one reason I said I couldn't help with anything else. In particular,
I can't really say what you need to do to configure PAP authentication
for a cell phone connection. In fact, I think there are at least some
cell phone ISPs with PPP implementations which require PAP responses
that pppd can't be configured to provide.
