Debian Installation :: Squeeze - Change Grub Password And Console Font Size?

I'm trying to do is protect the computer against housemates. The standard procedure I do with Lenny:

1. Password protect BIOS.

2. In BIOS, always boot from hard drive. Disable booting from any other device such as USB or CD-ROM.

3. Password protect Grub (v1) using the "password --md5 $1$9MuaA/$5TDLgvmcEiCWNr5W9VaMK1" syntax in my menu.lst file.

With the above precautions in place, [I think] the only way to gain root access to the system is to take the case lid off and proceed to do stuff physically (like set jumpers and/or take out the hard drive). Am I correct? My reasoning for this is, the computer boots -> must boot from HD -> must load Grub -> must go to default menu item since others are protected, and cannot command prompt in Grub without password.

Anyhow, In Squeeze, I was a bit disappointed to find out, after doing a bit of Google-research, that Grub v2 (which is standard on Squeeze now) does not easily support password protecting the Grub menu. Am I correct? Will this issue perhaps be addressed in the Squeeze final release? Is this feature dumb anyways because the Grub password is of no use (i.e. my paragraph above is complete horseradish)?

Another thing I would like to do is change the console font and size back to something more "normal" or "classic", not some crazy tiny font that's only found in totally bleeding edge Linux distrubutions <gasp!>. I found that the Squeeze console font (e.g. when I type Ctrl+Alt+F1) is wicked tiny. I wanna change it to "normal". Grub v2 password and console font config?
