Xtal frequency, baud rate, in-circuit programming.

Going to use a HC08 of some description in a new project, and this will have an SMD and use in-circuit programming. I have never done one like this before and the problem is this: I will be using an 8 MHz xtal but for programming, according to the datasheet it needs a 9.8304 MHz xtal for the sake of the correct baud rate between the pc and board. Can I just use my 8 MHz xtal and somehow use a non-standard baud rate or is there some other way?
