Hey Andrew,

As suggested by Randy Dunlap on the linux-ide mailing list 
(http://marc.theaimsgroup.com/?l=linux-ide&m=115082279504424&w=2),
I send you this patch Bruno Harbulot did on a previous 'really crappy' 
patch I did.

We've been testing it for a while, it works fine so we'd like to see it 
intergrated in your tree and maybe upstream later.

This patch allow the sata port of the ATIIXP chipset to work at 55MB/sec 
instead of 14.

Regards,
Erwan
