SATA/ATAPI

["Tais M. Hansen" <tais.hansen@osd.dk>]

Hi,

I know there has been some talking about SATA/ATAPI being experimental and 
might not work at all under kernel-2.6.x.

One of my linux boxes has a Plextor DVD-RW drive with a SATA interface. The 
kernel sees this drive (ata3) but apparently doesn't tie it to a sdx device. 
The box also have a SATA harddisk, which is working just fine. The relevant 
dmesg output is pasted below.

Is there anything I can do to help the development of SATA/ATAPI devices?
