ACPI Battery Problem wth 2.4.22-pre4

Hello,

I'm running 2.4.22-pre4 on a Dell Inspiron 5100 (with Debian/unstable).

It seem to work fine, except when I insert the battery, I get:

    ACPI-0352: *** Error: Looking up [Z000] in namespace, AE_NOT_FOUND
search_node c1594a80 start_node c1594a80 return_node 00000000
    ACPI-1121: *** Error: Method execution failed
[\_SB_.PCI0.LPC0.BAT1._BIF] (Node c1594a80), AE_NOT_FOUND
    ACPI-0352: *** Error: Looking up [Z000] in namespace, AE_NOT_FOUND

ACPI-1121: *** Error: Method execution failed
[\_SB_.PCI0.LPC0.BAT1._BIF] (Node c1594a80), AE_NOT_FOUND

Any ideas how to fix this?

[please cc me on replies!]

Thanks!
