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.

Any help is much appreciated.
