Re: pmspcv panic on boot on this box

Try the following patch. There’s a fundamental misunderstanding of newbus that’s screwing things up…

Also available at http://people.freebsd.org/~imp/patch-queue/pms

The problem is that the first time through for ahd0 we’re setting cardMap[0] to 5. The second time through it is  already 5, so we say ‘oh, this has been probed before’ and return 2. This causes antiapi_probe() to return 0, because the card has already been probed before. This is wrong on so many levels, but I’ll suppress channelling my inner bde and stop here.
