Hi folks,

I'm writing this mail as I'm discovering ACPI and framebuffer related probl=
ems
on my Acer TravelMate 800LCi notebook with Linux 2.6.1-rc1. First, it's goo=
d=20
to see that the synaptics-patches from -mm made it into the mainstream kern=
el,
they are necessary to make the synaptics work together with XFree here.

However, there is a problem with ACPI: /proc/acpi/processor/CPU0/performanc=
e,=20
which was there in previous versions of the kernel and allowed me to slow t=
he=20
CPU down in order to save power, disappeared in Linux 2.6.1-rc1. It's simpl=
y=20
not there anymore. Was it replaced? If so, what is the right way to do it b=
y=20
now?

Secondly, there also is a framebuffer related problem. I have VesaFB in kern
and pass 'vga=3D791' to it at boot time. However, at the time when it switc=
hed
to FB in previous versions of Linux, the screen by now simply stays black.=
=20
Is this a known problem and if so is a fix available?
