Patrick has the DViCO FusionHDTV Express DVB-T Dual Pro, which uses the 
same configuration as the DVB-T NANO, and the DD4, but using the CX23885 
PCI Bridge.  It's safe to assume that it uses the zl10353 demod, 
although we'll be screwed if DViCO went for the newer Intel version of 
that part.  (I've yet to see the zl10353 linux driver work for the Intel 

%Zulu885.DvbtDualPro%      =  Zulu885.DvbtDualPro,  

I'll work on a xc-zulu885.patch this week, which will depend on my 
xc-bluebird.patch, so you can test it.  In the meanwhile, the i2c_scan 
output will be helpful, so that I can determine which i2c bus I can 
expect to find the tuner hardware.
