Please tell me if I can now help. Myself I only know to try:
a) SATAPI UDMA DVD without CONFIG_SCSI_SATA
b) SATAPI UDMA DVD with CONFIG_SCSI_SATA, with compile-time options and
other patches applied near include/linux/libata.h
c) Add Di <= Hi PIO auto sense, now that we/ you have overcome:
--- http://kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.8-rc1
...
[libata] create, and use, ->irq_clear hook
...
On Intel ICH5/6, the BMDMA 'interrupt' status bit will be set even on
non-DMA commands, ... This change clears pending interrupts once upon
initialization, and then each ... ata_irq_on...

Please correct me if I err in thinking,
Still today in kernel.org Linux .config we choose one of two SATAPI
UDMA. The post:

tells us of an lk 2.6 SATAPI UDMA available near make defconfig when
CONFIG_SCSI_SATA is not set. But the focus of this "Subject: Re: Linux
Serial ATA (SATA) status report" thread is the Linux SATA/ SATAPI we
get when CONFIG_SCSI_SATA=y.

Easiest for me to try first was plugging an unreleased SATAPI device
into:
Linux 2.6.8-rc1-bk6 i686
After defining ATA_ENABLE_ATAPI ATA_DEBUG ATA_VERBOSE_DEBUG in
include/linux/libata.h, then still I saw the disappointing:
kernel: ata_bus_reset: ENTER, host 2, port 1
kernel: ata_bus_softreset: ata2: bus reset via SRST
kernel: ATA: abnormal status 0x80 on port 0xE007
kernel: ata_bus_reset: EXIT
I guess next I'll fall back to trying an old device, and if need be an
old kernel, to reestablish a base line. Til I have an interesting
question or patch to share, I may remember to blog how life goes to

Ahhh, trouble was,
Linux to SATAPI/ PATAPI bridge to PATAPI DVD choked over DVD ID jumper
set to 1. Change jumper to ID 0, and life is good again.
