Challenge 18F indirect addressing

The 18f452 has some really tricky ways to implement indirect addressing.
#define MAX_LEN 256
unsigned char arr[MAX_LEN];
unsigned int sum;
void array_sum(unsigned char len)
{
unsigned char i;
sum = 0;
for(i=0; i<len; i++)
sum += arr[i];
}
This can obviously be implemented in less than 12 instructions. How about
9?
