Description ajax at nwnk dot net 2004-06-01 08:01:40 UTC
originally
http://sourceforge.net/tracker/index.php?func=detail&aid=216018&group_id=387&atid=100387

In mga_drm.h comments indicate that only DSTORG and TEXORG is validated.
I think bit 15 (memreset) of MACCESS should be checked as
well:

"The memreset field must always be set to '0' except under specific conditions
which occur during the reset sequence."

Seems like something which should not be accessible to normal users.
