Turns out it's even simpler than I previously thought! The only problem seems to be the 1kHz initial clock rate in the driver. Not anything about number of line reset edges, that was a red herring (and improper power cycling was probably why I mis-diagnosed). Patch submitted as http://openocd.zylin.com/#/c/2223/ Technically speaking openocd still doesn't meet the datasheet's stated requirement of 150 clocks w/ SWDIO high to enable DAP. Stlink sends more than the low level driver does, but probably not 150 either, so perhaps it's not a problem - but I'm noting it here in case people are having intermittent trouble with nrf51822 DAP in the future.
