Existing IDE drivers are not going away any time soon (not 2.6.x at least)

from the kernel - IMHO it is quite easy to add CHS support to libata.
I also agree that libata PATA development should be focused on LBA
but I don't see any problem in keeping CHS support around...

I don't think it's a problem to support C/H/S in libata.  libata already 
has to handle lba28/lba48, CHS would simply be a third instance of the 
"fill read/write taskfile" code.
