I've applied your patch to my cxusb tree, with slight modifications. 
Please test the tree and confirm proper operation before I request a
merge into the master branch.


You'll notice that I fixed the dib0070.h and dib7000p.h headers to allow
cxusb the option of using DVB_FE_CUSTOMIZE, but when these modules are
selected, dvb-usb-cxusb is still static linked to them.

Perhaps we could put all of the dib7070p common setup into a dib7070p
module, to centralize the duplicated code between dib0700 and cxusb. 
This could also help to remove the static links described above.

I started playing around with this idea -- If I make any progress, I'll
post the tree and ask for testers.

I don't think that the static links are enough of a reason to hold this
patch back from a merge.  Hopefully we can find a solution before
2.6.28, but if we don't , it's no real harm done.

If you have any additional fixes / changes to make before this is merged
into master, please generate them against this cxusb tree.
