Hmmm. OP's problem is that his consoles are *not* 80x25; rather, they are closer to 64x250 (on his wide aspect ratio monitor). I believe he wants to change the resolution of the consoles, not X, to restore 'normal' 80x25 text mode. I have my 1280x1024 monitor 'set' to 64x160 (using an 8x16 or 9x16 font) because I want more information on the consoles. That's the mode of the console, which is independent of X. IIUC, the mode of the consoles cannot be changed after boot, though I could be wrong on this point. There *is* a parameter (vga=) that can be specified at boot or in LILO/grub that sets the console video mode during startup. But I can't recall how I did it. If he can find this parameter and set it, he may be able to set his console to display larger text. He might also be able to use 'vidmode' to set the default video mode in his linux image. There's a small chance he set the default mode when he configured his kernel. If he cannot find and set this parameter, he will be stuck with finding a larger font (perhaps 18x32) and using consolechars to set it on each of his consoles.
