 Thanks ! I found the problem :)
 As I mentioned above, I had tried with a kernel configuration (according 
 to http://svn.freebsd.org/changeset/base/222980) which deactivated all 
 intern sound drivers, resulting in the same panic error.
 However I forgot I had an USB headset plugged in. Therefore the kernel 
 loaded implicitly sound drivers attached to this device (in particular 
 sound.ko), before OSS starts.
 Unplug the USB headset solved the problem but one question remains :) 
 how can I disable this behaviour so that OSS manage my headset as well ?
