My .02: I think it's crucial at this juncture for people to not only 
say "it worked with those options" or "it didn't work with those 
options", but also make sure they indicate whether the boot messages 
(dmesg) show that indeed DMA was turned on when the options where 
added.

1) "dmesg >dmesg.old"
2) create/edit /boot/loader.conf.local
3) reboot
4) "dmesg >dmesg.new"
5) diff dmesg.old dmesg.new


For various reasons a particular hardware setup may not activate DMA 
mode even after adding the loader options because of things like BIOS 
settings, cabling issues or hardware bugs.
