FreeBSD 5.4-STABLE: DVD in PIO mode?

[O. Hartmann]

Hello.
After I did a cvsupdate today and recompiled world/kernel, I realized
that DVD/CDROM now is by default in PIO mode 4. I have to bring them
back to DMA explicitely by setting hw.ata.atapi_dma="1" in
/boot/loader.conf.local.

Is this right or is this a weird behaviour of the widely unsupported
(and therefore running in some GENERIC modes) ASUS A8N-SLI (nForce4
based Socket939 mainboard)?

Looking at dmesg output, the harddisk attached to the nForce4 SATA II
controler is said to be driven in UDMA33 mode by a GENERIC-ATA driver
for this still unsupported chipset. Can I trust this message or is it
simply a dummy message and the harddisk is driven as SATA150 (Maxtor
6B200MO, 200GB, NCQ capable)?
