I managed to get it to work:

# vim wv.conf

  [Dialer Defaults]
  
  Init1 = ATZ
  Init2 = ATQ0 V1 S0=0
  Modem = /dev/ttyUSB1
  Modem Type = Analog Modem
  Stupid mode = 1
  Dial Command = ATDT
  Password = ;
  Username = ;
  Phone = *99#
  Init3 = AT+CGDCONT=1,"IP","bredband.oister.dk"

# wvdial -C wv.conf

I was wrong about usb_modeswitch not being activated. It
is because its documentation states that a device,
/dev/gsmmodem, is being created and since it wasn't there, I
assumed that it had not been run, but it was /dev/ttyUSB1

Oddly enough, when I tried /dev/ttyUSB0 first with no response
and then changed to ttyUSB1, I got the error,

  "invalid dial command, ATDT*99#
	
i.e. wvdial somehow strips the space between the ATDT command
and the number so one must reset the modem and try again.	

Wvdial is a wily program ;)

Thanks,
Morten

PS: I tried to mail the wv.conf file to myself, but the mail
command wasn't there!
