At least as long as we don't build kind of a pseudo fb into the kernel,
which is not likely to happen soon. I'm not that happy with restoring the
palette unconditionally. In fact the newport driver once did that and I
removed the code. I'd really like to get the bug fixed once and for all.
Workarounds have the tendency to stay around forever. You said you have
some SGI guys at work, isn't there anybody who knows what the problem
could be? I running out of clues why we can't read back the palette. I
can write and read back other registers on the same chips without
problems only the palette registers seem to fail.
