According to the posts in the reference and my experience from
yesterday, it does not support that when it is running with 630 MHz
which seems to be the case with newer BIOS versions so with later
delivered models.

Is there a sysfs-entry? In 2.6.26 /proc is not supported anymore, is it?
So no /proc/cpuinfo?

These are the experience in the Internet too. That is why a think Asus
is underclocking the EeePC to 630 MHz in newer BIOS versions.

Does somebody have experience with detect-laptop?
