Sorry for the double post, but I used gmane to post this to debian-boot so there
was no copy in bugs.debian.org.

Before you waste your time this doesn't work. Once installed libata removing
and
reinstalling them has no effect :-(.

So I suggest two options:

1 - Ubuntu way:

    Enable ATAPI by default both in installer and in the target initrd. Ubuntu
    does this since hoary (kernel 2.6.10) without problems in my Dell Inspiron  

    9300. (I Can't say nothing about other hardware).

2 - Carefull way

    Enable atapi in the installer, detect CDROMS and if any of them is
connected
    to SATA enable ATAPI support in the target initrd.

Anyway I think ATAPI support will be enabled by default in 2.6.16 kernels as it
is considered production quality in 2.6.15rcX, see:
