            Status: UNCONFIRMED

When using kernel-image 2.6.12-8-386 with the p4_clockmod module, the file
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies shows 8
frequencies (312500 625000 937500 1250000 1562500 1875000 2187500 2500000) but
with the version 2.6.12-9-386 (or 2.6.12-9-686) this file shows only 2
frequencies (2187500 2500000). I am using an Acer TravelMate 240 and the
processor is an intel celeron 2.5GHz (details are below).
