4 questions:

1. Is <your_linux_kernel> configured to present IDE disks as a kind of 
SATA/SCSI disk (/dev/sda).

2. Is hda listed in the expected locations under /sys/ ?

3. Does "ls -l /dev/hda" report the correct major and minor device 
number as listed under /sys/ for hda?

4. Which version of qemu is this, they keep changing the command line 
syntax so fast even their own documentation cannot keep up.

Enjoy
