Thanks sjo.  Exactly what I was looking for.

I'm trying to get your last method to would, using the attribute.  
This is what I did for a test function:

void __attribute__((section(".data"))) IAP_Test( void ) {
  U32 N;
  N=IOPIN;
}  // IAP_Test

When I make I get:

main.o(.text+0x150): In function `main':
/cygdrive/d/GNUARM/Projects/Vader/main.c:96: relocation truncated to 
fit: R_ARM_PC24 IAP_Test
collect2: ld returned 1 exit status
D:\GNUARM\bin\make: *** [vader.elf] Error 1

The line #96 in main is where I put the call to IAP_Test().  GCC is 
taking the attribute, and seems to be doing something with it, but it 
is giving me this relocation error.  I don't know what R_ARM_PC24 is.

Do I need to allocate extra space for this in my startup.s file?

Can you give any help on this?  This would be great to get working 
with this method.  

Thanks,  Chris.
