regression in ata/atapi wrt dma?

[Michael Nottebrock]

I just noticed that one of my burners in my homebox isn't set to dma mode 
anymore on boot (hw.ata.atapi_dma="1" is set in loader.conf.local):

acd0: DVDR <HL-DT-ST DVDRAM GSA-4081B/A104> at ata1-master UDMA33
acd1: CDRW <HL-DT-ST RW/DVD GCC-4120B/2.02> at ata1-slave PIO4

I dual-boot 4-STABLE on this box and there it is:

acd0: DVD-R <HL-DT-ST DVDRAM GSA-4081B/A104> at ata1-master UDMA33
acd1: CD-RW <HL-DT-ST RW/DVD GCC-4120B/2.02> at ata1-slave WDMA2

I guess I can rule out cabling going loose or similar things...
