Indeed. I use UDMA on FreeBSD -current with some weird chipset (Linux
2.0 nor 2.1 could recognize it and thus hdparm -d 1 refused to turn on
UDMA) on a quite heavily loaded machine, without any corruption so
far. Using softupdates I read 12MByte/s (much more than my twice as
expensive fast-SCSI-2 disks).
I haven't heard of any FreeBSD user with such problems in UDMA.
I'm very pleased with it, my system boots at least twice as fast as
without DMA.
