So the Linuxolator is changing ioctl(2); that I would expect. What I
don't expect is it to change one ioctl(2) into a completely unrelated
one.

uvcvideo: uvc_v4l2_ioctl(VIDIOCGCAP)
uvcvideo: Unknown ioctl 0x40047601
uvcvideo: uvc_v4l2_ioctl(VIDIOCGCAP)
uvcvideo: Trying format 0x56595559 (YUYV): 10000x10000.
uvcvideo: Using default frame interval 200000.0 us (5.0 fps).

corresponds to

 86117 skype    CALL  linux_ioctl(0xb,0x80685600 ,0x2dc9e014)
 86117 skype    RET   linux_ioctl -1 errno 22 Invalid argument
 86117 skype    CALL  linux_ioctl(0xb,0x803c7601 ,0x2dc9e07c)
 86117 skype    RET   linux_ioctl 0

The ioctl(2)'s are completely different, and when I go and check the
lookup table in stable/8/sys/compat/linux/linux_ioctl.h, I find:

#define LINUX_VT_OPENQRY	0x5600
#define LINUX_VIDIOCGCAP		0x7601

Why is Skype sending a VT_OPENQRY, and webcamd receiving it as a
VIDIOCGCAP?
