Probably OK.

OOI, is the default mapping adequately useable on these cards? If not, I have
a patch (for budget-ci, intended for use with older Nova-T cards, but
probably adaptable to cx88) which will allow programming from userspace.
One of the keymap loaders in dvb-utils should be useable or adaptable.

w_scan? How does this differ from scan (in dvb-utils)?

Which modules are loaded? According to the kernel configuration help, you
want cx88, cx88-dvb and one of four front-end modules, in this case mt352 or
cx22702. (I don't know which; my Nova-T is older and uses tda1004x.)

Does that device node exist? If so, check the permissions. If not, the answer
depends on whether you're using udev.

Without udev:
  # cd /dev && MAKEDEV dvb

With udev: make sure that you're using the version currently in unstable. (If
you still don't get device nodes, proceed as for without udev.)
