Questions about some acpi-warnings

[Jürgen Dankoweit]

Hello to the list,

on my Thinkpad T43 I get the following warning in /var/log/messages 
while the notebook is in suspend mode:

acpi_ec0: warning: EC done before starting event wait
acpi_ec0: wait timed out (response), forcing polled mode

These two messages are displayed during boot time:
ACPI APIC Table: <IBM    TP-1Y   >
ACPI Warning (tbfadt-0505): Optional field "Gpe1Block" has zero address 
or length:        0    102C/0 [20070320]


What do this messages mean?

Many thanks for your answers.
