Quick work around is just shooting in continuous then letting the buffer catch up. I get the stated 10 RAW before the buffer locks out for about a minute.
If I recall correctly, the D1 bypasses the buffer and writes directly to the memory card while in Single shot drive mode; hence the delay, whereas shooting in Continuous mode it writes to the buffer. The solution (as you've found) is to shoot in Continuous mode even if only single photos are desired.
