Wow, I wasn't even aware that we have such magic in relatively new code
like -device. And that it's only effective for -device, but not -drive.
And to be honest, I really never wanted to know...
Anyway, you can't create an ide-hd on secondary master now because there
is the default CD-ROM already:
qemu-system-x86_64: -device ide-hd,drive=blubb,unit=0,bus=ide.1: IDE
unit 0 is in use
qemu-system-x86_64: -device ide-hd,drive=blubb,unit=0,bus=ide.1: Device
'ide-hd' could not be initialized
