I'm beginning to wish I'd just ignored the fact that we need a properly working "soft" reset to get back from 286 protected mode to real mode, and wired up the damn PAM reset unconditionally. I'm not convinced that the protected->real mode transition will work for anyone anyway.
I believe currently we must be somewhere "between" soft reset & hard reset. I estimate getting closer to a well-emulated hard reset is more important than getting closer to a soft one. If you were to extend the i440FX reset handler so that it unconditionally resets the PAMs, I'd give my Rb. (Take it for what it's worth :))
It would actually make sense. The right way to do soft reset has nothing to do with qemu_system_reset_request().
I've posted that version of the patch, with a suitable comment.
Thanks.
