Hello Tejun,
Here is the relevant dmesg output for my kernel with the PIIX IDE driver:
Linux version 2.6.32.9 (root@greer) (gcc version 4.3.2 (Debian 4.3.2-1.1) )
#1 SMP Wed Mar 17 20:21:58 CDT 2010

I must admit the CD-ROM drive is rather old, a late 90's model slot loading
Pioneer drive, but it works fine with the PIIX IDE driver. If it is needed
for success under libata, where would I set ATA_HORKAGE_NOSETXFER?
I have no problem continuing to use the PIIX IDE driver, but I understand
all of the old IDE drivers are or will be deprecated in the not to distant
future. This is why I tried to get the drive working under libata.
Thanks.
