As far I remember from the discussion on the linux-dvb mailing list this 
has been removed in the overhauling process because it unecessairily 
complicated the code and the proper solution is trivial to implement -- 
workarounds for broken EEPROMs that are easy to fix in userspace really 
don't belong in kernelspace.
