oh yes ! don't know for the other drivers, but dvb-ttpci is not
smp-safe at all. And unfortunatly dvb-kernel devs don't have a smp box
to work on it.
If you search dvb-kernel mailing list archive, you'll read smp and
dvb-ttpci users moved to single cpu.

concerning PREEMPT and HT i'm not sure, i had some issues with
a PREEMPT enabled kernel yesterday evening but it's possible it's
related to dvb_device_open problem i've reported on dvb-kernel ml.
