57  * TW says: This code looks awful, I know. But please don't do anything about
58  * this otherwise debugging will be hell.
59  * The code is extremely fragile as regards the different chipsets, different
60  * video bridges and combinations thereof. If anything is changed, extreme
61  * care has to be taken that that change doesn't break it for other chipsets,
62  * bridges or combinations thereof.
