In V.90, does the consumer modem have the same pretty-tight control over
speeds as in Flex? [The Flex way makes sense to me...it's the user modem
which sees the phone line.]

If so, the "USRobotics FaxModem ITU Standard and X2 technology compatible
56K" modem (that's a "longish" replacement for "Sportster") seems awfully
anxious to renegotiate. Sitting on a telnet session watching "my" modem in
the PM3, I can tell that *most* renegotiations result in the same speed
being picked at the end as at the beginning (discounting those show Mx
commands which induce another renegotiation). At least that's the case on
my Flex-free phone exchange.
