I tried the iHOS BD-ROM with a VIA VT6412 SATA controller today and it worked:

snippet from dmesg:

I also tried my sata_nv with a 64-bit kernel 2.6.22-3-amd64. I got
these messages where it looks like ata3 is finally reset and set at a
UDMA/66, but I don't get the drive recognized afterwards:

I contacted LiteON technical support in the meantime, but they are no
help. They said they tested with one Linux system and it worked.

I will probably buy one of the above VIA cards and use it for this drive.

Thanks for helping!
