Hi,

when I tried to compile 2.4.22-rc2 + ACPI 20030813 I got a compilation 
error in setup.c. Adding a CONFIG_X86_IO_APIC around the offending 
places fixed the problem. See the attached diffs.

Reading some recent messages on this mailing list, I think I should try 
to enable the kernel options LOCAL APIC and IO APIC for my laptop though...

Regards,

	Stefan
