more data:

- irq21 seems to always carry about half of the number of interrupts atapci1 is carrying.

- over large periods, the % busy of ad6 is at 100%, servicing maybe 350 or even 800 requests/sec.  I/O speed then is around 3-10 MB/sec.  this is with 1.10 and SMP.  I'll try compiling a old-ata kernel now.
