Hmm.  I have a PVR-500, with the extra input cable hooked up to unit #2
of the PVR-500 and a DTV-to-CVBS converter box connected.

My CVBS signal shows up when I am set to PVR-500  'Input 2, Composite 1'
which is cx25840 'Composite 3'.  This makes sense for unit #2 of a
PVR-500. It must have the white connector wired differently from unit #1
of the PVR-500 (and from the PVR-150), since the PVR-500 unit #2 doesn't
have a CVBS input connector on the main card.

Are you sure you have the input like this and obtain good video from
PVR-500 unit #2, when it is set to 'Input 4, Composite 2', cx25840
'Composite 4'?

Could you try recording with PVR unit #2 set to 'Input 2, Composite 1',
cx25840 'Composite 3'?  

These are the questions in my mind:

Is your PVR-500 unit #2 wired differently than mine?
Are the older kernels more forgiving when capturing audio with the wrong
input set? (Try both Input 2 and Input 4 with both kernels.)

The cx25840 blurts out IR unit status (ignore it) and the cx5840 user
controls (Volume, Balance, etc.) a little differently,

No.  They look the same for everything that matters.
