I looked through the file
before my initial post, looking at HVR-1800 support, and it looked
pretty complete for HVR-1800 (but not the 1880lp).
Steve Toth said analog worked fine for him on 2 March 2009:

but people are reporting some problems. It's not clear whether those
reporting problems have the latest drvier or not.
In my mind, the HVR-1600 is a safer bet for having it "just work".
A system level issue, that can happen to anyone with a PCI card like the
HVR-1600, though is sharing the CX23418 PCI IRQ line with some other
device that has a device driver with a poorly written IRQ handler. That
situation on a PCI bus can cause poor performance with the CX23418
firmware (which doesn't like being ignored for long). I'm not sure if
it can be an issue on a PCIe bus.
