ok... I think that's the reason why you are not encountering this problem, I 
hunted down the commit that caused it:
sos         2004-08-13 08:14:27 UT
  Modified files:
    sys/dev/ata          ata-all.h ata-chipset.c ata-dma.c 
  Log:
  Allow the use of a supplied function to set the PRD table. This is
  needed for new chips that supports 64bit addressing.
  
  Revision  Changes    Path
  1.81      +11 -4     src/sys/dev/ata/ata-all.h
  1.80      +5 -4      src/sys/dev/ata/ata-chipset.c
  1.129     +14 -30    src/sys/dev/ata/ata-dma.c

I haven't had time yet to make sense of what exactly might be wrong there but 
maybe Søren or someone else can make an educated guess faster than me :-)
