Ok.  That would mean to replace the option rom with a seabios patch. 
The qemu code will be unmodified though (except for the rom loading).

Huh?  Do you want export *all* block devices via extboot?  Will IDE 
drives show up twice then?

I would export only one and export it only on explicit user request, so 
it can be used for cases where seabios has no native support ...
