hw.ata.atapi_dma problem

Salve,

with today's -current (~21:30 UTC) I get hw.ata.atapi_dma listed again. But 
it's said to be 1 so dma should be enabled I think.
dmesg says:
Timecounters tick every 1.000 msec
GEOM: create disk ad0 dp=0xc2d97570
ad0: 39083MB <Maxtor 4D040H2> [79408/16/63] at ata0-master UDMA100
acd0: CDROM <SONY CDU4811> at ata1-master PIO4
pcm0: measured ac97 link rate at 55928 Hz

So dma is NOT enabled although the sysctl is 1

atacontrol mode 1 also tells PIO4
After "atacontrol mode 1 udma33 udma33" I get udma33 returned.

So whats's the truth? I think my cd-rom should be able to work in dma mode.
Mode tells me no dma is used and sysctl the opposite.
Of course I have the sysctl enabled in loader.conf!

Thanks,

-Harry
