Graphics problems with FreeBSD on Sun SPARC computer

I was trying to install FreeBSD 7.0 on an old Sun
Blade 100 computer (from 2002) which has an UltraSPARC
IIe 500MHz RISC CPU in it. But I can't get the
graphics to come up (I've only got text-console right
now on the OS.). How can I fix this?

When I try to do a "startx", the screen just goes to
black and the monitor light to yellow. Hooking to a TV
shows that at this point there is "NO SIGNAL". I can
"ctrl-alt-backspace" to shut down the X server and get
a command prompt.

The machine has an ATI chip of some sort inside, and
I've tried configuring X to use several ATI drivers
but all giving the same result.

Xorg.0.log contained various warning (WW) messages,
such as not being able to find "fonts.dir", the OS not
having counted the PCI devices and so was guessing
wildly, that an accelerated framebuffer could not be
shadowed, and that there was not enough video RAM
(required 12.8MB, card has only 8MB) to allocate a DRI
static buffer. Disabling acceleration with 'Option
"NoAccel" "true"' in the X config file under the
"device" section did not help, although it got rid of
the warning about not having enough video RAM. However
I then got warnings "ATI(0): Acceleration disabled,
not initializing the DRI" and 
"ATI(0): RENDER extension not supported with a
shadowed framebuffer".

What can I do to resolve this problem?
