How do you know?  I know because I've tried.  It's always the pppd
program and ConfigReq sent/received.

Do you mean a SDO spec says that PDP context is set up?  And that that
SDO document doesn't say 'ppp is used'?  I agree with this part.

What do you call a PPP ConfigReq within a MAC header with 48bits
addresses, as displayed by Ethereal?  And with a pcmcia card saying hsdpa.

> PDP context != PPP or PPPoE

I'm sorry.  PDP context is not something defined at IETF, a different
beast, can't compare.
