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.
