It strikes me that you have no driver loaded for your card;
your lshw has an almost-blank configuration line, mine says
        *-display
             description: VGA compatible controller
             product: NV43 [GeForce 6600 GT]
             vendor: nVidia Corporation
             physical id: 0
             bus info: pci at 0000:02:00.0
             version: a2
             width: 64 bits
             clock: 33MHz
             capabilities: vga_controller bus_master cap_list
             configuration: driver=nvidia latency=0 module=nvidia
so I can then do:
mark at dragon:~$ lsmod | grep nvidia
nvidia               8858052  34
i2c_core               28544  2 nvidia,i2c_nforce2
and see that my driver is loaded.

Having a different graphic setup, I don't know what driver you should
have - but you don't... so you're getting some poor default setting.

What does the GUI System>Administration>Hardware drivers look like?
If someone can tell you what you _should_ have, modprobe xxxx may be the
answer - I'd have a check in synaptic for 'intel' as well. I note that
the first item in mine is '915 resolution, a fix for certain resolutions
in Intel [945] chipsets'. also xorg-xserver-video-intel should be
present, I would imagine; Even I appear to have that!

If you re-boot and press F2/del during the RAM test phase, and look
around your BIOS, there may be a setting that disables video some; I
suspect this to be unlikely though.
