It's currently being developed, the hvr4000 tree is the best place to 
find any recent patches.

Not currently.

The kernel does not currently support this type of dynamic switching, 
for the HVR4000 or any similar product. However, the HVR3000 tree 
http://linuxtv.org/hg/~stoth/hvr3000 contains some prototype patches for 
an RFC I am about to release, suggest some kernel improvements to allow 
DVB-T and DVB-S to be used dynamically, with the hardware resources 
shared correctly.

If the RFC is goes through the review/revise cycle quickly then those 
patches should appear in the dvb tree soon, meaning that DVB-S, DVB-T 
can be used on both the HVR4000, HVR3000 and some Medion based Philips 

They are also dependant on Manu's multiproto patches, which are not 
currently accepted for mainline merge.
