CMD640 ide bug fix



The CMD640 ide controller works like a regular ide controller except
that it has a nasty bug whereby simultaneous access to the primary
and secondary controllers will cause data corruption.

Both FreeBSD and NetBSD fix this problem by preventing simultaneous
access.

I've scanned the sources (particularly wd.c) for a similar fix for OpenBSD
but it looks like there is none.

Is there a patch for it or any rumblings that it will be fixed in the
future?
