Can you disable timer interrupt on the interrupt controller, instead? Provides same functionality, and needs no runtime overhead...
On most PowerPCs, timer interrupt aren't an interrupt comimg from the interrupt controller, but their own processor exception triggered by the decrementer defined by the ppc architecture. Ben.
