14 Shouldn't I have 4GB minus the amount of graphics memory then, instead of
15 3G minus that?
16 But I plan to add more memory anyway. With at least 6GB, and better 8GB,
17 the graphics memory will not matter that much then. But I have to go to a
18 64bit system for this.

25 Good idea! Thanks, I will have a look there.

27 BTW, this is part of my lshw output:
28 *-display
29 description: VGA compatible controller
30 product: Radeon HD 3200 Graphics
31 vendor: ATI Technologies Inc
32 physical id: 5
33 bus info: pci@0000:01:05.0
34 version: 00
35 width: 32 bits
36 clock: 33MHz
37 capabilities: pm msi vga_controller bus_master cap_list rom
38 configuration: driver=fglrx_pci latency=0
39 resources: irq:18 memory:d0000000-dfffffff(prefetchable)
40 ioport:ee00(size=256) memory:fdfe0000-fdfeffff memory:fde00000-fdefffff
41
42 d0000000-dfffffff is 255M, fde00000-fdefffff is 1M. So I lose 1/4 G for
43 graphics memory.
