Hmm.

With -device and thus alot of device setup happening after 
QEMUMachine->init() I think it would be very useful to have 
QEMUMachine->init_late().  There are a bunch of machine specific jobs 
which need to be done after all devices have been plugged into the machine.

Setting up cmos is one of them.

i440fx_init_memory_mappings() could be moved there, which would allow to 
add vga cards via -device.

And I'm pretty sure there are more use cases.  fw_cfg maybe?

Comments?

cheers,
