Hi,

By the way, I have updated the documentation and the header files. Please do 
it next time.

Also I think there might be a problem with the PS/2 write: if the CPU is 
writing too fast, data will be lost. A solution is to add a "busy" flag in a 
register (like it used to be done in UART) that the CPU can poll before 
writing to the PS/2 port. A full interrupt-based FIFO like in the UART should 
not be needed as you write very little PS/2 data.

Sébastien
