It just so happins that I maintain the Linux IDE/ATAPI cdrom driver.  I 
chat with Mark Lord, "The Linux IDE guy", fairly often.  He has somebody 
looking into support for the new Ultra DMA/33 IDE stuff which is supported 
by the Intel TX and the VIA VP2 chipsets, among others.  If you just want
to drive a regular IDE or ATAPI device with one of these, you are just fine.
I, for instance, have a TX chipset motherboard running a couple of old IDE
drives.  To support the new Ultra DMA/33 stuff and get anything like the
claimed 33 MB/s, we need to add error handling for CRC transfer errors, 
and probably also need code to set the drive and chipset into Ultra mode.  
This stuff is in the making, but not done and ready for public consumption.
If you want more, ask Mark.  His email address is in the Linux maintainers 
list (right before my name [GRIN] ).
