There are reports of bringing it to working state, but it's still too much memory hog. For watching flash videos, microB is still recommended.
copy Your (Maemo's) [b]/usr/share/X11/xkb/symbols/nokia_vndr/rx-51 file into Your *debian's* /usr/share/X11/xkb/symbols/nokia_vndr. From within Maemo, when Debian is mounted and .chrooted, it's /.debian//usr/share/X11/xkb/symbols/nokia_vndr, where You should copy file to.
This way, you'll have exactly same hardware keyboard mapping, as in Maemo - of course, if You setxkbmap <your language> inside ED, or via Ed autostart script.
@setxkbmap us
In layout that is found default in ED (before You copy rx-51), @ is just blue arrow + shift + space. Blue arrow + space is TAB. Default config is actually very useful, and contain many symbols assigned to blue arrow + shift + key, but I think that everyone will like own mapping's most. /Estel
