Which kernel do you run? You do not seem to have any active framebuffer;
with standard Debian kernels you should see something like this:
May 16 17:44:13 pc0197 kernel: [ 2.492813] vesafb: framebuffer at 0xc0000000, mapped to 0xffffc20010580000, using 2560k, total 7616k
May 16 17:44:13 pc0197 kernel: [ 2.492823] vesafb: mode is 1280x1024x8, linelength=1280, pages=4
May 16 17:44:13 pc0197 kernel: [ 2.492829] vesafb: scrolling: redraw
May 16 17:44:13 pc0197 kernel: [ 2.492834] vesafb: Pseudocolor: size=8:8:8:8, shift=0:0:0:0
May 16 17:44:13 pc0197 kernel: [ 2.507373] Console: switching to colour frame buffer device 160x64
May 16 17:44:13 pc0197 kernel: [ 2.521802] fb0: VESA VGA frame buffer device
Do you see any framebuffer devices at all?
$ ls -l /dev/fb*
crw-rw---- 1 root video 29, 0 2009-05-16 19:43 /dev/fb0
I did notice the absence of vesafb in your lsmod output, but this is
normal for the stock Debian kernels (vesafb is compiled into these
kernels).
If you rolled your kernel then you have to watch out for vesafb and
nvidiafb; for comparison, here are the settings for the standard
2.6.29-2-amd64 Debian kernel:
$ grep -E 'VESA|NVIDIA' /boot/config-$(uname -r)
CONFIG_FB_BOOT_VESA_SUPPORT=y
CONFIG_FB_UVESA=m
CONFIG_FB_VESA=y
CONFIG_FB_NVIDIA=m
# CONFIG_FB_NVIDIA_I2C is not set
# CONFIG_FB_NVIDIA_DEBUG is not set
CONFIG_FB_NVIDIA_BACKLIGHT=y
CONFIG_BACKLIGHT_MBP_NVIDIA=m
