fastest PWM clock source in 56F805

It appears that the only clock source for the PWM unit is the IPBUS, which is always 1/2 the chip operating frequency (section 11.5.2). My chip is running at 80 MHz, so I get a 40MHz clock at the PWM unit. I need a faster PWM clock speed, for smaller pulse-width deltas at high pwm rates. Is there any way in the 56F805 to clock the PWM unit at the full chip operat
