Kernel panic with ACPI and IBM Thinkpad

[Matthias Schmidt <schmidtm@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

my IBM Thinkpad T43 paniced after I resume the machine from sleep (ACPI 
S3).  I can reproduce the panic easily (just Suspend/Resume :)  I run a 
GENERIC kernel (DragonFly 1.3.6-DEVELOPMENT).

Fatal trap 18: integer divide fault while in kernel mode
instruction pointer     = 0x8:0xc0498c62
stack pointer           = 0x10:0xceb8492c
frame pointer           = 0x10:0xceb84948
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, IOPL = 0
current process         = 665 (acpiconf)
current thread          = pri 38 (CRIT)
