Changing keymaps

[Warren Block]

What does it take to reliably change to an alternate keymap immediately? 
kbdmap and variations of kbdcontrol -l aren't making any difference, 
although somehow yesterday they did.  At one point, anyway.

Using Bulgarian BDS (bg.bds.ctrlcaps.kbd) as a test, "a" and "q" 
reversed positions, shift-zero became "=", and so on.

But I can't replicate that now.  The Handbook L10N section on 
console setup says that kbdmap should work:
