Thanks for this, but I'm afraid I'm kind of missing the background
here.  I'm not very familiar with how the CHS-guessing works.  Perhaps
you could explain ?

Also, have you looked at upstream qemu to see what is done there ?
We're currently working on a merge of qemu-dm back into upstream qemu
and if possible we'd like to avoid adding more interface
incompatibilities.

Ian.
