This is going to put trouble in other places unless, at least, it can be 
turned off.  The UART serial interface is heavily emulated as a console 
interface without an actual serial port behind it, both in hardware and 
software.  Rates will typically vastly exceed real serial port rates, 

Yes Dell do it, HP do it, IBM do it. Have done for years, never caused us
a problem. Its only KVM tripping it.

As to bit rate we support up to about 1 to 1.5 Mbit.

FWIW, the highest rate I've seen in hardware is a FIFO about 4K deep 
that can be polled at about 25 MHz when all the overhead is accounted for.
