New User Stupid Questions on images.

Hi,
  I've just gotten the board and just got the tool chain working. I've read
though the material/manuals, etc.. got a  handle on the basics. But what I
wasn't able to find anywhere is info on the various linux builds (Config
Files).   I figured out that anything with 7 in it is for the 7" monitor
and 35 is for the 3.5" panel, and the config_mini2440_vga1024x768 is for
the external VGA. Aside from that could you let me know 

(1) Before I blow everything away on this, what is on it as a factory fresh
board? (I have a G540 [checked] on the side of the box, its a 3.5 LCD touch
on the mini2440 board). 

(2) Any explanation of the different .config file images? i.e. what's the
difference between n35 and t35 and what is the qq designation, another
board?  Thanks

config_mini2440_a70
config_mini2440_n35  
config_mini2440_t35
config_mini2440_vga1024x768  
config_qq2440_a70
config_qq2440_n35  
config_qq2440_vga1024x768

A momentary intelligent thought crossed my brow. I diff'ed the two config
files.. there was only one difference between the config_mini_2440_n35 and
the config_mini_2440_t35.  That difference is the frame buffer drivers,
apparently ( CONFIG_FB_S3C2410_N240320 - or - CONFIG_FB_S3C2410_T240320).

The *_N240320 is apparently for an 8" 800x480 LCD panel (should have ended
the config file with an "80" to stay consistent. Where the _T240320 was set
for the 3.5" LCD panel.. otherwise no difference. 

Hope this helps someone else..
