Boot time driver conflict

I have a Microdia web cam. Some times it won't work if and only if there is a "HV7131R image sensor detected" statement in the boot up.
In this case when I try to get a .png snapshot all I get is a frame full of what appears to be white noise only it is mostly green.
Here is the command I am using:
TV="-tv driver=v4l2:device=/dev/video${vd}:width=320:height=240:norm=NTSC:chanlist=us-cable:input=0:noaudioSmilieutfmt=i420"
OUT="-fps 30 -cache 128"
PIC="-hue 0 -brightness 0 -contrast 0 -saturation 0 -aspect 4:3"
mplayer tv:// $TV $OUT $PIC -vf screenshot -vo xv,x11,
This does not work when ${vd} is 0 or 1 and it is using HV7131R.
If it is not using HV7131R it works properly.
I think I am getting either gspca or HV7131R usage defined at boot time. Is there a way to force either one so I can test?
Hope it is OK here as the problem occurs in my script.

SBP_TARG(4)						   BSD Kernel Interfaces Manual 					       SBP_TARG(4)

NAME
sbp_targ -- Serial Bus Protocol 2 (SBP-2) Target Mode devices driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device sbp_targ device firewire device scbus device targ Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5): firewire_load="YES" cam_load="YES" sbp_targ_load"YES" DESCRIPTION
The sbp_targ driver provides support for SBP-2 target mode. This driver is supposed to work with cam(4), targ(4) and firewire(4). You also need to use scsi_target(8), which can be found in /usr/share/examples/scsi_target, to provide actual devices. EXAMPLES
# mdconfig -a -t malloc -s 10m md0 # scsi_target 0:0:0 /dev/md0 (Assuming sbp_targ0 on scbus0) SEE ALSO
cam(4), firewire(4), targ(4), camcontrol(8), fwcontrol(8), kldload(8), scsi_target(8) AUTHORS
The sbp_targ driver was written by Hidetoshi Shimokawa. BUGS
This driver is currently under development. It does not work correctly in multi-initiator environments or after the bus topology has been changed. BSD
