For 1024x768 and 32-bit color depth you'll need 1024x768x32 bits = 1024x768x4 
bytes = 768x4 KiB = 3x256x4 KiB = 3x1024 KiB = 3 MiB.  So, you'll probably 
need 3MiB of video memory.  You could run in 8-bit mode though; them you'd 
only need 768 KiB.

Besides not having enough video memory, it's possible that X is detecting the 
amount of video memory you have incorrectly.
