burncd 'blank' not terminating ?

just noticed, after upgrading to 6.2RC1, that

	luigi# burncd -f /dev/acd0 -v blank
	blanking CD, please wait..

stays there forever. Eventually i gave up and ctrl-C and
the application terminates, and i was able to write to
the disk a valid image, which probably means that the
disk had been blanked.

I browsed through the mailing lists and it seems to be an
old problem, related to the driver not reporting the status info.

Not sure if it is related to particular hardware, just in case here
is what i have:

ad0: 238475MB <MAXTOR STM3250620A 3.AAD> at ata0-master UDMA100
acd0: DVDR <HL-DT-ST DVDRAM GSA-H10N/JL10> at ata0-slave UDMA33

note, if i kldload atapicam, and try the blank on /dev/cd0 i get this:

	luigi# burncd -f /dev/cd0 -v blank
	burncd: ioctl(CDRIOCGETBLOCKSIZE): Inappropriate ioctl for device

Any ideas ?
This old report says the problem is in the ioctl...
