I have the following hardware in my SMP x86 system. When a DVDRAM disk is inserted into the PD-2 LF-D100 drive the system cannot correctly mount it. If an attempt is made to access the directory that is created with the volume name of the DVDRAM disk an error box with title 'Error - Konqueror' is displayed with message "No media in device for /media/DVD_01".

Since the DVDRAM is a vfat file system it seems to be that:
hal-subfs-mount[7684]: Collected mount options and Called(0) /bin/mount -t subfs -o fs=cdfss,rw,procuid,nosuid,nodev,exec,utf8=true /dev/sr0 "/media/cdrecorder"
indicates that hal-subfs-mount should be calling /bin/mount with the fs=vfat option/value pair.
