Ultra-Sparc IIi, debian 6.0.3 - cant get picture from webcam logitech c170

[Arkhipenka Stanislau <dise.logo@mail.ru>]

Hi, debian-sparc. Im trying to connect logitech c170 to server. It 
successfully mounted to /dev/video0, but i cant get picture. I tried to get 
picture with fswebcam, and got message to syslog:

Jan 11 15:55:26 SunFire kernel: [1512592.827475] compat_ioctl32: unknown ioctl 
'V', dir=6, #26 (0xc050561a)
Jan 11 15:55:26 SunFire kernel: [1512592.919494] ioctl32(fswebcam:21335): 
Unknown cmd fd(3) cmd(c050561a){t:'V';sz:80} arg(ffa954f8) on /dev/video0

Also i tried applications: webcam and zoneminder. It dont work too. I tried 
this webcam on debian amd64 and i386 and it works fine. 
I have v4l on my sustem:
~$ find /lib/ -iname *v4l*
/lib/modules/2.6.32-5-sparc64/kernel/drivers/media/video/v4l2-int-device.ko
/lib/modules/2.6.32-5-sparc64/kernel/drivers/media/video/v4l2-common.ko
/lib/modules/2.6.32-5-sparc64/kernel/drivers/media/video/v4l2-compat-

/lib/udev/v4l_id
/lib/udev/rules.d/60-persistent-v4l.rules

Searching in google gave no results.
Can anybody help me to find solution of this problem?
