This seems to be a Good News (tm).

So if at boot we check writablity of bit 2 and 3 we can know if this
mechanism is implemented or not ?

We can do the test at trap_init() level. So we know how to (or not to)
deal with NMIs.
Just another thing. Can we rely on the bit 7 of the port 0x70 ?

Ciao,
Riccardo.
