What graphics card do you have? What version of X
window do you have?

I have an nVidia Riva card with 32Mb ram. I did
cat /proc/pci
and found this

  Bus  1, device   5, function  0:
    VGA compatible controller: nVidia Corporation
Vanta [NV6] (rev 21).
      IRQ 10.
      Master Capable.  Latency=248.  Min Gnt=5.Max
Lat=1.
      Non-prefetchable 32 bit memory at 0xf4000000
[0xf4ffffff].
      Prefetchable 32 bit memory at 0xf2000000
[0xf3ffffff].


I found the memory size by taking away 2 hexadecimal
numbers like so: f3ffffff - f2000000 = 1ffffff
1ffffff is 33554431 bytes, which is 32MB (this is the
"prefetchable" memory)

You could check the size of your video memory like
this.

Hope this helps.
