configuring shells at tty1 to tty6

[fmdf at tiscali.it]

Hello.

I'd like to login and to use shells at terminals tty1 to tty6, but before I 
can do it I need to solve two problems.

The first is about the size of characters (resolution?). They are too large. I 
recall that when I used Slackware and booted with LILO I could set that 
property (I am not sure now, but I think with "vga=nnn"). How can I do that 
in FC2 with GRUB?

The second problem is with console messages. I can't work with the 
above-mentioned terminals because they print a lot of console messages.
I know that I can write "dmesg -n 2", but I would like to regularly have them 
in tty12 to be read. How can I configure the log daemons at startup in order 
to send all critical messages (the ones with a level up to 'n'?) only to 
tty12 and to let the other terminals free from noise?

I thank you all. Ciao,

Fabio
