So what's the significance of "no extra SSDT table"? Does that mean that XP
and Linux are using the same tables to check for freq scaling support?

Thanks. I just looked at the kernel.org kernel (what's the term used
in lkml for this?) and found out the switch.
I got the kernel.org kernel compiled with the .config used for the F9
kernel. Now I need figure out how to get it to boot.

Btw, on your suggestion, I opened a bug for this issue.
http://bugzilla.kernel.org/show_bug.cgi?id=11299

Does the LKML community consider the Fedora 9 kernels as too different?
I would prefer using the F9 kernel for testing this issue since it's
easier for me to compile and install.

I got some important stuff to deal with for the next couple of days.
So I will get back on this thread in 2-4 days.

Thanks,
SK
