Hi,

I've implemented Colemak support for the GRUB bootloader, using the setkey command.  Simply put the code on top of your menu.lst file.

(Run the setkey command without arguments to fall back to Qwerty.  You could even make a menu entry for this.)

Now you can enjoy Colemak on your pc as early as in the bootloader.  The only thing still missing is the BIOS. :-)
(The NetBSD bootloader can be switched to Colemak too, see the 21/05/2009 post in this thread.)
