is it possible to patch scan2 for dvb-s2 support ?

> Here are some important pieces of information for you to know:
> current supported modulations with supported hardware:
> DVB-S, DVB-S2, DVB-T, DVB-C, DVB-H
> How big is multiproto?
> It's not. It doesn't exceed the size of the legacy api and is infact
> smaller when used in non-legacy mode.
> Does it support ISDB-T, ATSC-MH, CMMB, DBM-T/H?
> Intentionally, no! Experience with the old api development has proven
> that making blind assumptions about delivery systems is a bad idea.
> It's better to add in support for these when the hardware actually arrives
> and can be properly tested. There is enough reserved space in the api to
> support future modulations.
> current supported chipsets/devices:
> STB0899 based cards (AD SP400/VP-1041, TT S2 3200, KNC1 DVB-S2 etc.)
> drivers currently in development:
> STB0900/STB0903 based (eg. SAA716x based cards: AD SE-200/VP-1028, etc.)
> To clear up some misinformation and misconceptions:
> Is multiproto backwards compatible with previously built binaries?
> YES! You don't need to do anything to make it backward compatible.
> Does multiproto have support for drivers found in v4l?
> YES! Multiproto includes the v4l tree as well. However, the software
> you use must support the multiproto api in order to use them.
> Fortunately many already do but in the event support for the api must
> be added, it can usually be done with minor changes.
> Are new modulations possible?
> YES! Multiproto has been designed so that adding new future
> modulations may be done with minimal effort. This will help speed up
> the driver development process and allow us to use this api for some
> time to come.
> If you would like to use any of these drivers now, you may pull the
> tree from http://jusst.de/hg/multiproto. Drivers may be configured
> with 'make menuconfig' the same as you've done with v4l.
> Feedback, bug reports, etc. are welcomed and encouraged! Please feel
