SoftwareSerial and atmega 48

Does anyone know off hand if it is possible to run 100K Baud SoftwareSerial ( http://arduino.cc/hu/Reference/SoftwareSerial ) on an atmega48 clocked by a 7.3728MHZ crystal? The linked page says it is possible for speeds up to 115200 baud but doesn not mention hardware requirements. Apologies if I posted this in the wrong area.

thanks, Brendin
