Unfortunately that's just the size of the address space that the card 
is allocated, and may be viewed as the maximum amount of RAM that the 
chipset can support; it does /not/ mean that you have that much RAM 
physicall present on the card. Even the original 32MB GeForce2 MX 400 
cards shipped with the first IYONIX pcs consumed that much address 
space, if memory serves.

If you're running Geminus then you can use the command *GeminusInfo to 
list the amount of memory as reported by the NVidia driver module, 
which may or may not be the correct amount of RAM physically present 
and available for use. It's the last number in the 'Screens' section, 
alongside 'range.' Take the 3 leftmost digits (they're in hex) and 
convert if necessary... but 01F = 32MB card, 03F = 64MB, 07F = 128MB 
card. Some of the RAM is reserved for other use such as cursor DMA, I 
believe.
