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.
