Hair splitting: it looks as though Andre Hedrick's IDE patch did this at
least. Of course, that does not affect SCSI drives, but since you wrote
"Linux", I thought this could be mentioned in this thread again. At
least, my ATA drives are powered down some seconds before my ATX PC is,
and the kernel says about flushing the cache.
