Screen resolution with X 4.01

[Bob Nielsen <nielsen@oz.net>]

I finally was able to get a display with the new X, but I can't get it
to work with any resolution greater than 800x600 (16bpp).  With 3.3.6 I
am able to get 1024x768.  My video card uses a Cirrus 5430 and has 2MB
of video memory.  The messages I get for 1024x768 are:

(WW) CIRRUS(0): Default mode "1024x768" deleted (bad mode clock/interlace/doublescan)
(WW) CIRRUS(0): Default mode "1024x768" deleted (bad mode clock/interlace/doublescan)
(WW) CIRRUS(0): Default mode "1024x768" deleted (bad mode clock/interlace/doublescan)
(WW) CIRRUS(0): Default mode "1024x768" deleted (bad mode clock/interlace/doublescan)
(WW) CIRRUS(0): Default mode "1024x768" deleted (bad mode clock/interlace/doublescan)
(WW) CIRRUS(0): Mode "1024x768" deleted (no mode of this name)

I'm using the same monitor settings as with 3.3.6, 

        HorizSync       30-70
        VertRefresh     50-120

In addition, when X starts I hear what sounds like a relay clicking
inside my monitor and the screen flashes a bunch of vertical lines near
the top of the display.  None of this happens with X 3.3.6.

Does anyone have a suggestion for the problem here?
