Isn't this problem unrelated to this patch?  I mean if I start qemu with
two ide devices can I specify from qemu command line which one I want to
boot from?

That's sort of what I'm asking. If you compare this approach to extboot, extboot provided a capability to select a disk. I think it can be argued though that this isn't a necessary feature to carry over and I'm looking for additional opinions on that.

I'd say it's a necessary feature, but not one to carry over from the extboot implementation. We have the seabios boot menu (how to reach it?), we need to store the nvram persistently, and we need to extend the selection menu to qemu, but that's unrelated to this patch.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
