Will this be coming out in a paperback edition or just hardcover?   ::)

LoL, I was thinking of something along the lines of "Your GPU appears to be broken"

I thought in that case BOINC doesn't see the GPUs at all, though Windows does?

Here's an oldie but a goody  http://setiathome.berkeley.edu/workunit.php?wuid=730523283 I know the first one was showing a couple of no heartbeats but it looks like it finished and had the same count as everybody else. Wonder why he didn't get any credit?

I would have to check to be sure on that, but I believe everything appears normal under enumeration, except once in the application you can't initialise the selected device (cudaSetDevice() ) due to permissions or the device already being allocated to another (presumably the user) session somehow.   If that is really the case, then the approaching move to the boinc_temporary_exit() feature should help out, indefinitely stalling the work.
