using microSD card shield #254 with DUE

[ghjmaui]

I would like to use my microSD breakout board (part #254) with the Arduino DUE, which is 3V3. The DUE has the standard ICSP header for SPI, but it wires 5V to the VCC pin. It appears that the ICSP lines on the DUE go directly to the ATMEGA CPU. If I connect the 254 pins (DO, DI, CLK) to the SPI pins on the DUE, should I also connect the ICSP 5V to the 5V input on the 254? If I do this, won't the 254 convert MOSI/MISO/SCLK to 5V going into the DUE? Or should I wire 3V3 explicitly from the DUE to the 254 3V3 input, and bypass the ICSP 5V VCC? I don't want to have a voltage problem between MISO/MOSI/SCLK on the DUE and DO/DO/CLK on the 254. Thanks.

The level shifting on the SD breakout is one-way from high to low. So the Due will always see 3.3v signals.
