Atapi CDROM, SATA OS drive, and 2.6.14+ kernel

[andyliebman]

Can somebody tell me what changed in the 2.6.14 kernel that doesn't 
allow me to access my CDROM drive when my OS drive is SATA?

I have an image of a working 2.6.14 system that was installed on an IDE 
drive. I restored the image to a SATA drive, changed a few lines in 
/etc/fstab and /etc/lilo.conf so that they refer to /dev/sd* devices 
instead of /dev/hd* devices.

I also modified /etc/modprobe.conf so that it is identical to the file 
that Mandriva 2006 produces when installed directly to a SATA drive 
(but Mandriva 2006 has the 2.6.12.x kernel).

I can't mount my CDROM when running 2.6.14.x

I have googled this for several days. I have seen posts about passing 
options to the kernel and including extra lines in modprobe.conf like:

libata atapi_enabled=1

Can't find the magic formula. Help would be appreciated.
