No problem. The compiler will use include files (e.g. 8052.h) or other settings to know about the specific processor properties as memory sizes and special function registers.
ya got to know... but you can use c51 compiler with keil microvision2 from the keil website given by FVM... in that page select the evaluation software and then download c51 compiler and start working....
