ACPI help needed

[Nathan]

I've got a curious problem on my hands (I think. Maybe somebody can fix 
it in an instant):

the latest ACPI patch refuses to build with my box.

Under gcc 2.95.4 I get:
ld -m elf_i386 -T 
/home/expsoft/src/linux-kernel/linux-2.5/linux/arch/i386/vmlinux.lds -e

drivers/acpi/acpi.o(.text+0x28667): undefined reference to `__ucmpdi2'
drivers/acpi/acpi.o(__ksymtab+0x208): undefined reference to `acpi_exit'

And under 3.0 (debian unstable latest, 3.0.4-pre020127), the errors 
about __ucmpdi2 disappear, but the acpi_exit one remains.  acpi_init, 
which is a very very similarly defined, constructed, etc function is 
fine.  Somebody please help me (my system depends on ACPI PCI IRQ routing).
