Greetings:

Thank you for the tips!!!

I went and tried this using this kdbcontrol command in my .cshrc:

# added to increase scrollback to 1000
/usr/sbin/kbdcontrol -h 1000

This gave me 1,000 lines when I'm logged into the console however, it 
resulted in a "Inapproriate ioctrl for device" error when using xterm 
(xfterm4) under xfce4.

So I removed the "kdbcontrol" from my .cshrc and used a "-sl 3000" 
option to launch xfterm4.

So launching "xfterm4 -sl 3000" now does the trick!
