Subject: [x86] blacklist systems that need nommconf
Message-id: 47BCA6D9.7030104@redhat.com
O-Subject: Re: [RHEL 5 PATCH]: Blacklist Montpelier & Johannesburg Systems to disable mmconf
Bugzilla: 433671

RHGD requires that these two systems boot.  Currently, they only boot if
pci=nommconf is specified on the command line.

DMI match on the board names of these systems and automatically disable
mmconf.

Tested on the Montpelier & Johannesburg systems by me.

Resolves BZ 433671.
