Cannot unload if_iwi module

Hi,

when I try to unload if_iwi module, here is what happens:

% jarjarbinks:/<3>dev/iwi:118# kldunload if_iwi
% iwi0: detached
% jarjarbinks:/<3>dev/iwi:119# iwi0: <Intel(R) PRO/Wireless 2200BG> mem 0xc8218000-0xc8218fff irq 11 at device 3.0 on pci6
% iwi0: Ethernet address: 00:12:f0:2c:f3:6e
% iwi0: [GIANT-LOCKED]

The kld is reloaded automatically (I am sure it is reloaded because
the id showed in kldstat(8) changes each time):

% jarjarbinks:/<1>share/mk:137# kldstat
% Id Refs Address    Size     Name
%  1   20 0xc0400000 4ef910   kernel
%  2    1 0xc08f0000 e5dc     if_bge.ko
%  3    1 0xc08ff000 4ce4     ums.ko
%  4    1 0xc0904000 b180     umass.ko
%  5    2 0xc382e000 25000    linux.ko
%  6    1 0xc38cb000 2000     rtc.ko
%  9    1 0xc3acf000 e000     if_iwi.ko
% 10    2 0xc3add000 3000     firmware.ko

% jarjarbinks:/<3>dev/iwi:122# kldstat
% Id Refs Address    Size     Name
%  1   19 0xc0400000 4ef910   kernel
%  2    1 0xc08f0000 e5dc     if_bge.ko
%  3    1 0xc08ff000 4ce4     ums.ko
%  4    1 0xc0904000 b180     umass.ko
%  5    2 0xc382e000 25000    linux.ko
%  6    1 0xc38cb000 2000     rtc.ko
% 11    1 0xc3acf000 e000     if_iwi.ko
% 12    1 0xc3add000 3000     firmware.ko

Any clue how to disable this unwanted behaviour ?

Thank you.
