Yes.  You can use the compiler for any LPC chip, for any ARM7 for that 
matter.

When creating a new solution I suggest choosing a target chip that has the 
same memory map as the LPC2148 (LPC2138 looks like a good candidate from a 
quick scan of the Philips WEB site, and is an option in CrossWorks), then 
the project should have the startup code and linker setting you need 
automatically.

Slightly different syntax required for:
+ ARM/THUMB interworking,
+ declaration of interrupt service routines
+ intrinsic functions.

Generally it is straight forward.

Have not used it but looks similar:

Just use a GCC port, it will work with CrossWorks.  I think there is also an 
LPC2148 FreeRTOS.org port in the files section of this group.
