I see the same firmware loading issue. I assumed the problem was in tuner_xc2028, as I don't see any related messages in dmesg after the firmware blob fails to load:

The firmware file /lib/firmware/xc3028-v27.fw belongs to the linux-firmware-nonfree 1.14.ubuntu1 package. I have located instructions on the origin of this file (http://www.linuxtv.org/wiki/index.php/Xceive_XC3028/XC2028#How_to_Obtain_the_Firmware) and I have verified that the firmware file is identical to the one obtained by that method. The DViCO FusionHDTV card has been used for several years in this machine. This problem only occurred after upgrading to saucy salamander.
