I guess I have to apologize for claiming too early that I have a SS24X:
S o r r y , I g o t i t a l l w r o n g .

I do NOT have a SS24X running, but I have a SpeedStar 24 PLUS!

But I am able to use 1152x900i and 1024x768ni.

And, yes, I do it without the clock program (yet) by just starting Linux
into VGA Mode 1 (see /linux/Makefile:

---># If you want to preset the SVGA mode, uncomment the next line and
---># set SVGA_MODE to whatever number you want.
---># Set it to -DSVGA_MODE=NORMAL_VGA if you just want the EGA/VGA mode.
---># The number is the same as you would ordinarily press at bootup.

--->
--->SVGA_MODE= -DSVGA_MODE=1

) and using the following Xconfig (for the OLD Xfree86, not V1.2):
