Hi,
The 128 Mb aperture is the maximum amount of system memory the AGP can 
use as graphics memory, it's using 8Mb currently (but it can use 128 Mb 
max). you can usually adjust aperture size in your bios.

ehm no, that's not quite correct...it's using a maximum of 128 Mb of 
system memory as graphics memory as said before, AND 8 Mb of stolen 
memory (I think..., used as framebuffer?, to do all vga/vesa modes?)

To be honest I read about the intel graphics and how they work...but can 
quite remember it (brain probably did not use enough stolen memory)

thanks for the info..
my bios only has settings for 1Mb and 8M. Ive got it set to 8Mb now..
so If in my xorg.conf, I haveVideoRam32768
does this influence what the video card will use? I have that in my 
config now.. can I tell how much memory my video card is using?
 

Yes, if you set it to  1 Mb you probably can not go above 640x480 24bit 
colour in X, I think 1024x768 max but only at 8 bit colour, so 8 Mb is 
better.
As far as I know it's best to leave the VideoRam setting in xorg.conf 
commented out, In most cases the driver detects the memory X can use. 
The setting influences how much memory X uses for video modes, setting 
it too high can cause problems.
