[pptp-server] 2.4 woes

I'm having this basic problem using pptp with linux 2.4.1: it doesn't
work. (syslog included below:)

After a little research tonight (reading the list archive) I realise
one of my problems at least is likely to be my using pppd 2.3.11 (vs
2.4.0 which I should have).

I selected a 2.4 kernel before considering the pptp issues because it
supports my ide controler natively (an HPT366 on an ABIT MB), I would
need to find a patch to use 2.2.

My basic question is is it going to be easier to downgrade the kernel
or do people have 2.4.1/ppp 2.4.0/pptpd working well now?

Secondly, I'm just trying with standard kernel/pppd at the moment, no
encryption.  When I go to using encryption, can I build all the needed
drivers in to the kernel, or do they need to be modules?  I prefer to
have my kernels setup without modules if possible.

Finally, I'm using standard debian packages, I'd be interested in
other debian users' experiences, and to know if there are debian
packages floating around for mschap/mppe enabled kernel/pppd.

Here is my present configuration:

Win98        Internet       Nokia         Linux Router       Private
Client  ---            ---  DSL Box  ---  PPTP Box      ---  network

The nokia pinholes (reverse masquerades) the tcp control conection and
proto 47 (if I have it set up correctly).

Here is the extract from the logs:
