Some more experiments resulted in the following: The card
works *exactly once* after booting.  When I leave X and
start it again, the machine freezes.  Actually, all video
modes (including the second above) seem to work (I tried
about five), but all of them work only when the card is
`freshly' booted.  I guess that it is the probing of the
clock that freezes the machine when it is done after I have
started X already once.  In particular, if, after starting
X, I run `turboxcfg' to set up video modes, the machine
already freezes after the dialog where I have to select the
color depth -- `turboxcfg' seems to probe for the possible
video modes, which I guess requires probing the clock.

Apart from this problem, everything seems to work fine, even 
the acceleration (though I have a slight distortion on the top
1cm of the screen image, which I cannot remember to have
seen before installing the new server). 

> When you run at 1280, which dot clock does it use?

I append the output of the SVGA server below (but for
1152x900 -- otherwise, I have to boot again, and somebody else
is currently also logged in).  It says

  (--) SVGA: Maximum allowed dot-clock: 135.000 MHz

I guess, the server probed for this value?  Can I just tell
it the value, so that it doesn't probe?  (I didn't find any
such option in the manual -- but maybe I just didn't
recognize it.)

Any idea why the card behaves differently the second time I
start X?

Thanx,

Manuel
