SubjectInvalid PBLK length for athlon XP-M on Asus laptop
My laptop is an Asus L3100 with an AMD Athlon XP-M 2000. ACPI says it
has only C1 power state:

# cat /proc/acpi/processor/CPU0/power
active state: C1
default state: C1
bus master activity: 00000000
states:
*C1: promotion[--] demotion[--] latency[000] usage[00000000]
C2: <not supported>
C3: <not supported>

and
# cat /proc/acpi/processor/CPU0/info
processor id: 0
acpi id: 1
bus mastering control: no
power management: no
throttling control: no
performance management: no
limit interface: no

Since this is a laptop it seemed a bit strange to me 8), so I checked
dmesg with acpi debugging turned on (full dmesg is attached), and I
found these:

[.....]
ACPI: Fan [FAN0] (on)
acpi_processor-1626 [30] acpi_processor_get_inf: Invalid PBLK length [5]
ACPI: Processor [CPU0] (supports C1)
ACPI: Thermal Zone [THRM] (44 C)
Asus Laptop ACPI Extras version 0.24a
L3D model detected, supported
Notify Handler installed successfully

[.....]

NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
acpi_processor_perf-0104 [28] acpi_processor_get_per: Unsupported address space [127] (control_register)
cpufreq: No CPUs supporting ACPI performance management found.
ACPI: (supports S0 S1 S3 S4 S5)
[.....]

Is there something I can do to add support for this laptop ? I'm not
feeling confortable with a battery that lasts ~40 minutes...

Everything else works fine, even swsusp and additional leds thanks to
acpi4asus. I'm using 2.6.0-test4, but I tested also 2.6.0-test3 and
2.5.72.

Other /proc/acpi files follows.
