Not all mappings are supported, most languages come only with one encoding since this should be sufficient to get up & running in using sysinstall, and we are already pretty tight on space. (My previous commit has already bumped the boot MFS size by another 50 KB for this.) This feature requires the `kbdcontrol -L' i've just committed. Plain text keymaps and the entire scanner are overkill for sysinstall. Also updated the list of available keymaps while i was at it. Reviewed by: jkh
