Well, edid has extensions, so it can become pretty large in theory, and
I've figured it would be a good idea to leave some room just in case.
It should be a rather infrequent operation, so the unused buffer space
should not hurt much.
Yes, it will be a edid generated by qemu. The current generator code will
use at most 256 bytes.
cheers,
Gerd
