Note that, paradoxically, including the procedural _PRT will cause
Igor's approach to fail, and the only way to fix it would be a similar hack.

But actually Igor's patches make the dependency on the precise table
size much smaller; for example a test like "if (version <=
pc-i440fx-2.0) add 1500 bytes of padding to the tables" would work.
