No problem. I asked for your opinion. :)

Yea, I did see that wait for !BSY in ata_std_prereset() and remember
wondering why it was turned off for ahci where it would have nicely
solved the problem. I actually considered inserting the short wait
there (i.e. the change you suggest below) but since the problem
appeared to happen only during initialization I thought it might be
better to put it in a less frequently visited ahci-only place.

I could give them a try but it seems unlikely that they will show
up in all of the soon to be released Distro updates we're worried
about.

This definitely works for me if the other information I included
in this message doesn't change your mind.

0x80
I believe I tried with GoVault attached to each of the 4 ports
and always saw 0x80. Below is my ugly 2.6.20-rc6 debug output
(hard drive on ata2, GoVault on ata3) that may be of interest.
