Hi,
I've read your article (http://forums.gentoo.org/viewtopic.php?t=178018)
and did the steps you said- but it doesn't work.
I'm running gentoo with kernel 2.6.6-rc5 (mm-sources) and powernow is
compiled into the kernel.
Adding "powernow_k7.powernow_acpi_force=1" to the kernel command line
changes my dmesg output to:
PowerNOW! Technology present. Can scale: frequency and voltage.
powernow: FSB: 99.557 MHz
powernow: PSB/PST known to be broken. Trying ACPI instead

but minimum speed is, as you, see still ca. 1GHz, under win I was able
to clock down to 233MHz.
My Computer is an Asus L2400D with an Athlon Mobile XP 1600+
I hope this helps
Sincerly,
