Oh, we're running kernel threads already for quite some time: the process
reaper, the pcmcia port managers, the update-replacement, usb handling
threads and probably some others:

root         1  0.0  0.0     0    0 ??  ?W<  -          0:00.00 (init)
root         2  0.0  0.0     0    0 ??  ?W<  -          0:00.00 (pagedaemon)
root         3  0.0  0.0     0    0 ??  ?W<  -          0:00.00 (reaper)
root         4  0.0  0.0     0    0 ??  ?W<  -          0:00.00 (ioflush)
root         5  0.0  0.0     0    0 ??  ?W<  -          0:00.00 (usb0)
root         6  0.0  0.0     0    0 ??  ?W<  -          0:00.00 (pcic0,0,0)
root         7  0.0  0.0     0    0 ??  ?W<  -          0:00.00 (pcic0,0,1)

(output a bit unusual because my ps here operates on /proc right nows ;)
