thanks for the tip. I've switched to using the wvdial scripts from

http://julian.coccia.com/blog/index.php?m=200503&more=1

and now everything's working fine.

well almost fine; despite setting noauth in /etc/ppp/peers/gprs, it 
still wouldn't work without a dummy username and password in
gprs-wvdial.conf

My provider, Orange, doesn't need authentication, but doesn't seem to 
mind if you stick some random entries in the file to keep the script happy.
