Speakup on AT91RM9200

[Leigh Harrison]

Please, can anyone help with this problem?
I have installed a patched kernel with Speakup 2.0 on a Kwikbyte  
KB9200 Evaluation board. Initilally, I had a compile errors due to  
SERIAL_PORT_DEFNS was not being declared for the AT91RM9200  
architecture. I have created a local drivers/char/speakup/serial.h to  
overcome this problem. it now compiles and runs as long as the  
default synthesizer "none" is selected.
A kernel panic results if any other default is chosen and compiled  
in. See boot up sequence below:
