Whilst I haven't used a modem in a long time, I recall that fiddling
with MTU/MRU issues often helped. Try giving the pppd options 
'mtu 576' and 'mru 576' (either put them in /etc/ppp/options, or
/etc/ppp/peers/<provider>, or whatever other script launches pppd
for your connection), and see what happens.

You should also be able to see the modem chatting in syslog (maybe
you need to turn use the debug option in pppd, or pass -v to chat?)
then hopefully you can see the CONNECT XXXXX line showing you the
modem speed. There might be an init string you need to turn it on to
show it, google should know :) But then you'll know if it's a line
issue (if the connect speed really is low), or a software issue (bad
packet fragmentation or something).

Sorry about being vague - it's been a while since I've used one :)

Bernard.
