libata PATA patch for 2.6.16-rc5

[Chris Boot <bootc@bootc.net>]

Hi Alan,

2.6.16-rc4-ide2 correctly identified my HP Colorado tape drive (which  
I haven't had a chance to use yet...), but 2.6.16-rc5-ide1 doesn't at  
all:

I'm guessing it's the PIO error, but I really don't have a clue.

HTH,
Chris
