I went back and rebuilt the kernel, modules and recompiled
the i830 module.  That made the XFree error go away, the
i830 module loads and Card0 was indeed created.  X starts
with no complaints.  That's the good news.

The bad news is that's there is no improvement in the
performance.  When using a display depth of 8, gamma is
adjustable but the graphics are grainy and there are not
enough colors available.  Depth over 8 gives good texture
and color but the gamma is too high and not adjustable.

I don't know if the chipset or the driver are at fault
here although I suspect the driver.  I'll have to try
to adjust gamma under Windows.  All in all I'm not
impressed with this setup under linux.  I'll post to
comp.os.linux.x and email Intel.
