How to update the hardware database for autodetection?

hi,

     I have a bt878 based capture card that required additional options 
to make it work under debian/knoppix. However , knoppix 3.3 would just 
simply modprobe the bttv without any options. Result that the system 
take several minutes to initialize the bttv module but in fact it don't 
work.

     Although I can specific the options through the kernel cmd 
interface , I would like to update the knoppix's hardware database 
directly. So that I can contribute my work for next version of knoppix.

Thanks for any advise.
