DxO's P-Mpix is an area measure, not a linear measure like lp/mm or lp/ph.

Not sure what it actually measures in any quantifiable way. They have not told us. We do know though that it is certainly not a measurement of actual resolution.

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)

Yes, would be nice if they told us a bit more about how the P-Mpix score is derived, but it's easy enough to translate P-Mpix to a linear measure. If a 3:2 sensor + a lens 'resolves' for example 6 P-Mpix, then that's the same as saying that it resolves 2000 lines vertically (lw/ph) and 3000 lines horizontally (lw/pw).
