About a year ago, I stated I was going to add the DVB API v5 additions. Well, you see how far that has gotten: nowhere. :P So please, your are welcome to help. > * Looking at the current kernel sources, the properties > DTV_DISEQC_MASTER, DTV_DISEQC_SLAVE_REPLY, DTV_FE_CAPABILITY and > DTV_FE_CAPABILITY_COUNT don't seem to be implemented.

I have no comment on these at the moment. I'd need to look into things and get back to you. > * Is the "v5 API" for frontends only, or is there a similar key/value > system in place/planned for the other DVB components such as demuxers? As far as I know for the DVB v5 additions, that came from what was originally called S2API, yes, they are only for frontends. Some additional ioctl()'s related to the demux have been added as well and are unrelated to the S2API additions.
