I think you'll find the baudrates in that list are validated via other files. So, I think you'll need to do (a little) more.

I've successfully added a custom baudrate to the standard Nios UART peripheral in this way. For that, as well as the '.tcl' file, I had to modify the 'class.ptf', 'em_uart.pl' & 'em_uart_qsys.pm' files - although each only to add the custom baudrate as an simple integer value. From memory, Qsys refused to generate until these changes were made.

Cheers,

Alex
