unexpected panic in idle process (RELENG_5 2005/04/25UTC)

I've been running RELENG_5 -D2005/04/25UTC on a CF-based system
(PC Engines WRAP.1C v1.03; 640 KB Base Memory; 130048 KB Extended Memory)
CF:	01F0 Master 848A Hitachi XX.V.3.4.0.0
	Phys C/H/S 978/8/32 Log C/H/S 978/8/32

...
CPU: Geode(TM) Integrated Processor by National Semi (266.64-MHz 586-class CPU)
  Origin = "Geode by NSC"  Id = 0x540  Stepping = 0
  Features=0x808131<FPU,TSC,MSR,CX8,CMOV,MMX>
...

after a few hours (mainly idle and ntpd), I was surprised to note
on the console:

Fatal trap 9: general protection fault while in kernel mode
instruction pointer     = 0x8:0xc05e8ca2
stack pointer           = 0x10:0xc7499d10
frame pointer           = 0x10:0xc7499d10
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 11 (idle)
[thread pid 11 tid 100003 ]
Stopped at      cpu_idle_default+0x5:   leave

I've got:

db>

unfortunately, I won't be able to take a dump because the CF has
no swap.

Anyone have an idea what this could be, and what I could type into
db> to get further info?

One thing that I changed on this HW yesterday was to add a Mini-PCI
HiFn card:

hifn0 mem 0x80040000-0x80040fff,0x80000000-0x80000fff irq 12 at device 13.0 on
pci0
hifn0: Hifn 7951, rev 0, 128KB sram

before that change, earlier RELENG_5 systems didn't demonstrate
any such an "idle" panic on said HW.

non-verbose dmesg and kernel config image are available, and I will
leave the db> there, awaiting suggestions.

This is an odd one; the IA32 manual doesn't say you can take a GPF from a
LEAVE instruction in protected mode. %ebp looks correct so I'd wonder if
you have cooling problems or a bad processor.
