ACPI problems

[Derek Tattersall]

I have and IBM G40 laptop, P4 etc, with the T3 default kernel 
Linux lapdog.arm.org 2.4.22-1.2088.nptl #1 Thu Oct 9 20:21:24 EDT 2003
i686 i686 i386 GNU/Linux
I get messages like the following small sample:

I am not very familiar with ACPI, but without acpi=on, the battery
applet doesn't work,  With acpi=on I not only get the errors listed
above, but the keyboard is very "jumpy", i.e. it randomly doubles or
more characters, or pauses in taking input and displaying it.

Any kernel gurus care to hazard a guess as to what's happening here and
how I might fix it?
