Hi Tobias
The support for ATAPI over SATA is there, however since it is still quite buggy, it is disabled by default.
You can enable the support by replacing "#undef ATA_ENABLE_ATAPI" in /include/linux/libata.h in you kernel source, with "#define ATA_ENABLE_ATAPI"
Personally I've noticed that since linux-2.6.9-bk3 it have been working without almost stalling the kernel.
Be aware though, that the support is apparently still somewhat limited. At least just about everything but ordinary mounting and handling of CD-ROM's
on my DVD (also on SiI3112) causes the applications to stall until a couple of timeouts have occured. So no DVD viewing and no burning, but ordinary
CD-ROM handling is working.
