Well, in that case we don't know what the solution is yet for dealing with
that bug in the chip.  If you read the registers, it fucks up on some 
machines.  If you don't read it, it fucks up on other machines.

For now, I think we'll aim for not reading, since then the machine doesn't
hang.

See if you can figure out what it it; you've got the machine...
