1GB limit

Try "ls /boot/" to see which kernels are installed.  You can find the 
name of the currently running kernel using "uname -r".

You most likely want linux-image-686 if you are currently running as 32 
bit.  (if the output of uname -m is not "x86_64" and something like 
"i686")  You can install this with 'apt-get install linux-image-686'.

Which video card do you have for the monitor?  (which driver is listed 
in your xorg.conf or XF86Config)
