I, think

writel(AT91C_PA23_TXD2, AT91C_PIOA_OER);

is the most correct way. 
But, there are need some additional def's in AT91RM9200.h. 
Only the port A registers is defined as pointer variable. 
If you think also this is the right way, I will send a 
separate patch for AT91RM9200.h (PORTB .. PORTD, SMC registers)

Best regards,

Jens Scharsig
