I confess I had some trouble applying the patch -- some filename issues, maybe
my own inexperience with pointing `patch` to the destination path -- but after
the import, sound from HEAD now works perfectly.  Thanks again!  :)  

[This with SMP and APIC_IO on, and the device happy on IRQ 3, for those keeping
track.]


Anyone know if FreeBSD had, or was likely to have had, the same problem with the
earlier code, or was it specific to the initial DragonFly port?  Just asking for
educational purposes, in case I try to learn myself something by reading all the
diffs.
