XFree86 difficulties

[LM]

I'm trying to figure out if I can get X running on my system and could use
some help.

I have an ATI All-in-Wonder 128, AGP card with 32MB.  I also recently
purchased a Sony SDM-X72 TFT LCD Color Monitor with specs of:
Horizontol Freq: 28-92kHz
Vertical Freq:56-85Hz
Max Resolution: 1280x1024

I tried configuring XFree86 through /stand/sysinstall.  Found suggestions
in the Usenet Newsgroups to set the card as ATI Rage 128 (generic).  I
tried that setting along with the various default screen types (VGA, Super
VGa, Extended Super VGA, etc.).  When I try startx, the screen displays
the message that I'm out of scan range and displays frequencies
35.5Khz-87Hz.  Does anyone know if I can get X Windows running with my
current hardware?  Any suggestions on setup?

I guess I should also mention, I installed FreeBSD from a CD with
release version 4.3.  Wanted to get some idea of how it would work with my
current system, before I go out and buy CDs for version 4.9.

Thanks.
