the patch changes the api...

you can try the attached patch, which not changes the api. that means szap2 is 
working (only DVB-S, for DVB-S2 you need to modify fe_params: DVB_FEC_AUTO is 
not supported and you have to define a modulation) 

fe_params.delsys.dvbs2.fec = DVBFE_FEC_9_10;
fe_params.delsys.dvbs2.modulation = DVBFE_MOD_QPSK;

with the attached patch you need to call DVB_SET_DELSYS (like in szap2)...
