SD 1-bit SPI mode can be implemented at the max SD speed, of course 
dependent on your peripheral clk speed setting.  You would need to bit bang 
the 4-bit mode.  There are some Fast GPIO registers implemented that make 
bit banging more manageable than the standard GPIO.  Using Fast GPIO you can 
toggle a pin in the neighborhood of 15.38MHz.  SPI0 has no FIFO, SPI1/SSP 
has two seperate 8 byte FIFOs for rx and tx.  Be sure to examine the LPC214x 
user manual.
