The best way is to use the 11.0592MHz crystal... Then you can easily get ALL the baud rates..

You have to use below settings

TMOD=0x20;
PCON = 0x80;
TH1=0xFF;
SCON=0x50;
TR1=1;

It will give you 57600 baud rate with 11.0592 MHz, then you have to use 22.1184 MHz crystal
or you have to set clock bit in P89V51RD2 with 11.0592 MHz crystal.
