Comment 160 for bug 127101

The loops aren't disabled in all cases. They program the 256 palette registers of each chip pipeline back to those read in before the X11 server started. Without this, your console palette is corrupted.

The woraround for the bug means we only actually ptogram the palette for the pipline which the console is using. (Any enabled pipeline actually). If we program a pipeline disabled in the chip, it locks the computer.

The bug may not be evident on machines with two displays active (on different pipelines).
