If it was going to be that easy I'd have done it myself ;-) AFAIK there isn't 
a simple ubx utility that would allow us to send parameters to the GPS and 
watch for the returning messages, so adding a few lines to ogpsd is probably 
the easiest approach. For anyone who knows their way around ogpsd and ubx it 
should be quick and easy ;-) I'm not that person, so if I get round to it it 
may take a little longer...
