O-Subject: [RHEL 5.4 PATCH]: Add xw8600 and xw6600 to GPE0 block blacklist
Bugzilla: 475418
RH-Acked-by: Neil Horman <nhorman@redhat.com>

HP xw6800 and xw8800 systems have strange Product Names in their DMI tables.

Add them to the GPE0 address register blacklist.

Tested on HP xw6800 (during testing I hit another unrelated issue) -- but
the patch does resolve the GPE0 register errors.

Resolves BZ 475418.
