Jonathan, thanks, i see.
I Tried enabling de aac driver in the GENERIC and RAMDISK_CD , and made
a release. It's still not showing it as enabled when booting with this 
new cd.
Could it be possible that the driver is another one?
I am writing an email to Adaptec right now asking for the documentation
you need.

Regards,
Marcos Laufer
