hsfmodem not compiling

I'having trouble compiling hsfmodem (running hsfconfig after succesfully installing 
hsfmodem_7.68.00.09oem_i386.deb) on a debian testing/unstable (originally a knoppix 5 install) with a 
2.6.29-1-686 debian kernel. 
alsa-driver-linuxant_1.0.19.4-1_all compiled without problems.
Running on a Dell Inspiron 1501 with a HDA modem.

Am thinking that maybe I should recompile the kernel as a more vanilla flavour (get rid of smp as its not 
needed, for a start?)
any thoughts anyone? thanks,

peter.
