The file vesafb.txt is from the documentation bundled with the kernel source. 
Heres an excerpt from vesafb.txt that documents the possible VESA video 

    | 640x480  800x600  1024x768 1280x1024
256 |  0x301    0x303    0x305    0x307
32k |  0x310    0x313    0x316    0x319
64k |  0x311    0x314    0x317    0x31A
16M |  0x312    0x315    0x318    0x31B

I don't know anything about Kubuntu's kernel configuration, but you can check 
the output from the vesafb kernel code by running 'dmesg | grep vesafb' in an 
terminal to verify that the kernel supports vesafb and can access the video 
memory direct.
