The fact that the UART of the CF card sais it would run at 115kbps does
not at all mean that the actual data throughput is only 115kbps.
For example we have a Brainboxes CF card which you set to 115kbps but
actually uses 1Mbps between the UART and the CSR chipset then. The UART
clock is simply higher so that a devider for 115kbps results in 1Mbps.
Only if your OS tries to setup something based on the baudrate you would
be in trouble here. Linux has no problems with the extra bitrate.
