I tried disabling both p4tcc and acpi_throttle by putting the following 
in /boot/device.hints:
hint.p4tcc.0.disabled="1"
hint.acpi_throttle.0.disabled="1"

It reduced the number of levels, but I still don't have a level 2000 as 
I used to get:
dev.cpu.0.freq: 1500
dev.cpu.0.freq_levels: 1500/-1 1200/-1 1000/-1 800/-1 600/-1
dev.est.0.%desc: Enhanced SpeedStep Frequency Control
dev.est.0.freq_settings: 1500/-1 1200/-1 1000/-1 800/-1 600/-1
