No it isn't. You need a custom kernel. IMHO everybody needs a custom
kernel. The installation ones are bogged down by drivers required to
support every known boot device. And you look in .config, if it's been
kept.

I doubt it.

I don't think there's any connection. I think defaultroute and proxyarp
are on in PPP by default, which leads to much mystification when people
read messages about them in the logs in circumstances where they're not
used.
ppp is not built into bo installation kernels, but I guess it might be
in more recent ones as I think that's now a supported method of
installation.
