One very simple workaround (albeit fiddly) would be to allow the user to *tell* the camera what aperture the lens is set to. In other words, make the f-stop indicator blink in 'M' mode with an M/K/A(in non-A). If you dial in the correct number that you've got on the lens, the camera knows everything it needs to do everything. Granted, it requires setting the f-stop correctly in two places, but it would be a simple thing to do. With that, stop-down metering wouldn't even be necessary with an A in non-A or a modified K/M.

Gack..

It actually wouldn't be that bad. In some ways, it's even less of a kludge than the stop-down metering. If it were a modified (with insulators) lens, or an 'A' in non-A, it could read absolute aperture. If used with a plain M, it could be relative... i.e. stops from full-open. Then there would be very little functionality lost... basically you get Av mode rather than only M mode.
