I get the same behavior (quietly failing) when pppd is not run setuid root.
I fixed it (at least before I switched to Debian which works out of the
box, so I recommend that you install it) with the command:

chmod u+s /usr/sbin/pppd

The other problem ("Sorry - this system lacks kernel PPP support") I have
experienced when pppd tries to start when the modem is already locked with
another pppd. This seems to be a cosmetic bug in either the kernel, or
pppd but I never bothered to find out which. This is a failure of either
pppd or the kernel to describe the actual problem, and instead defaulting
to the `lacks kernel PPP' message. I suspect it is a pppd problem though,
so you might try the ppp mailing list instead.
