still the same on hardy 2.6.24

# modprobe longhaul
FATAL: Error inserting longhaul (/lib/modules/2.6.24-16-386/kernel/arch/x86/kernel/cpu/cpufreq/longhaul.ko): No such device

# grep -i longhaul /boot/config-2.6.24-16-386 
CONFIG_X86_LONGHAUL=m

I guess this won't get fixed in anything but the newest kernel release.
Marking linux-source-2.6.15-22 as wontfix.
