Edit /etc/lilo.conf and change
vga=something

to
vga=ask

Run /sbin/lilo and reboot.

Now when you restart it should show the compatible VGA modes. Eg:

1.  80x25
2.  80x43
3.  132x25
4.  132x43

Remember the precending number on the mode you want to use and after you've rebooted you should edit /etc/lilo.conf again and change
vga=ask

to
vga=your_chosen_number

Run /sbin/lilo again to install the new settings.

does it only take effect on local console ?
What about remote console e.g. telnet

It's only on the local console. In remote sessions it is up to the client program to adjust it's window. For example PuTTY can be resized anyway one likes.

As for telnet, you really shouldn't use it anymore. If the server has an sshd-daemon running then you should use SSH.

Anyways, try to download PuTTY at this site:
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

It supports both telnet and SSH protocols.

If you want to resize the console on telnet/ssh session between two Linuxes/UNICES then I unfortunately don't have the answer.

Prolly the easiest way to resize a telnet screen is to use the above suggestion on the remote machine as well presuming of course that the telnet is from the CLI. If not, we'd need more info, such as the WM and Xwindows versions used.

I'm not so sure of RH7, but this works in Mandrake 8.0:

Run setup (in Mandrake that's located at  /usr/X11R6/bin/setup)

Choose "Boot configuration" and from there you can choose "LILO with text menu". I'm sure RH has something similar.
