My brand new Dell Latitude C640 oopses on boot in 2.5.56 if I
 have CPU_FREQ config'd in. ACPI without CPU_FREQ is okay - well,
 it screws my framebuffer screen (what 2.4.21-pre3 doesn't) when
 the ACPI code does its bootup printk's, but after that the
 screen recovers.

Another thing is that /proc/acpi/fan is empty despite my setting
 of CONFIG_ACPI_FAN=y.

Oh, and one more - /proc/acpi/battery/BAT0/state claims

charging state: unknown

 as well as

present rate:       0 mA
remaining capacity: 0 mAh
present voltage:    0 mV

 and the info file, when cat'd, prints a few times

dsobject-0188: *** Warning: Buffer created with zero length in AML


Back on topic, if you're interested I can rebuild my 2.5.56 with
 CPU_FREQ and write down the backtrace of the oops.

Sigh :(

Rebuilt with CPU_FREQ, doesn't oops. It says

cpufreq: Intel(R) SpeedStep(TM) for this processor not (yet) available

Is the above message expected ? The CPU is a 1.8Ghz mobile P4.

Still puzzled as to why... wait, this was a cold boot, let me try
 warmbooting... argh - the disk powered off. Bug 119 :(
Nope, coldbooted in 2.4.21-pre3, rebooted in 2.5.56, still had no
 oops with a CPU_FREQ enabled kernel.

How exactly does it fail?

We can just test if the rotation hook exist for the fbdev driver. No hook 
then use generic code in fbcon. Also we have a angle field in var so we 
can see if the user wants the data rotated.

I have that patch. It just has to be updated to the latest changes.
