I have no ideas for this case, but I will think.

#define DMA_DISABLE_INTERRUPT { read_creg(%imask, imask_tmp); bitclear_creg(%imask, 15); }
#define DMA_ENABLE_INTERRUPT { write_creg(%imask, imask_tmp);}

is this enough? I used it to disable interrupt while managing SDRAM transfer. But I always enable it once transfer is done. If I disable it completely, it wont crash then? How about this screen refresh, it refreshes screen after main() is ended. Are you uploading graphics directly to LCD_DATA memory?
I have disabled timer interrupt too.(all interrupts at all)
I am using LCD_DATA port to generate bitmap and I do not use SDRAM yet.

No wonder why, if you can manipulate sys freq in game Another improvement would be turning off the screen. I was messing around with the screen, and I managed to manipulate backlight driver of the screen that it can gradually get darker or brighter but I don't know if it can be introduced to RKP platform because of different LCD drivers (tested only on mine).
I do not know how to do it yet
