ata.c and sata disks

[Vega]

Hi to all,

I tried to modify ata.c simply add more ioaddress (I attach the diff file
from 1.96 version), and it work and recognize
my four sata disk on different pc. If I try to change sata port, the name
of device on grub change because it depend by index of ioaddress
in grub_ata_io_address array. 
There is some reason because ata.c currently report thar support "only two
ide drives" ? the driver seems work well... I can read file for my
partition, and then boot linux and even windows with chainloader. (i.e.:
chailoader (ata4,1)+1 and boot)

and forgive me if I write something of stupid...
bye
Marco
