Run-time selection of pc386 BSP console

[Eric Norum]

I've got an embedded processor module (PC-104) with no video adapter.  I 
now use gdb to poke the BSPConsolePort and BSPPrintkPort values to 1 and 
0, respectively, but this is a bit of a pain.  I think that it would be 
more useful to have the pc386 console driver detect the fact that 
there's no video adapter present and automatically switch to the 
serial-line console.

Something in console_initialize like:
	if ((BSPConsolePort == BSP_CONSOLE_PORT_CONSOLE)
	  && (<<<NO VIDEO DRIVER PRESENT>>>)) {
		BSPConsolePort=BSP_UART_COM2;
		BSPPrintkPort= BSP_UART_COM1;
	}
	

My questions are:
1) Do others think that this is a good idea?
2) What code goes in the <<<NO VIDEO DRIVER PRESENT>>> expression?

Thanks,
