Well, memory entries are added by QEMU, why not let the BIOS probe for 
that?  Plus, I really doubt that BIOSes on real systems probe for this.  
I'd guess they are hard-coded.

The user can pass the I/O base and IRQ values in on the QEMU command 
line, and they can be arbitrary values.  The BIOS is not going to be 
able to probe for those.
