You can remap one of the unused advertising keys (those that
are for "Windows" to be an additional space key.

The keycode should be 115 or 116 or similar. I can't check as
I do not own ANY keyboard with "Windows" keys on it. You can
easily find it out by (installing and) running

	% xev

and pressing those keys - the number will then be displayed,
and by default, a key symbol should be assigned. Here's an
example:

KeyPress event, serial 27, synthetic NO, window 0x1200001,
    root 0x73, subw 0x0, time 18453834, (43,160), root:(203,623),
    state 0x10, keycode 115 (keysym 0xffe7, Meta_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 27, synthetic NO, window 0x1200001,
    root 0x73, subw 0x0, time 18453902, (43,160), root:(203,623),
    state 0x18, keycode 115 (keysym 0xffe7, Meta_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

This is the left Meta key on the Sun USB keyboard I'm currently
using: Its keycode is 115, the symbol currently assigned is Meta_L.

If you would want to make that an additional space "bar", create
~/.xmodmaprc and code

	keycode 115 = space

Your X startup file (~/.xinitrc or ~/.xsession) should load this
file if present:

	[ -f ~/.xmodmaprc ] && xmodmap ~/.xmodmaprc

This would be a simple workaround for nonworking keys.

Same here, 

	keycode 115 = Control_L
	keycode 116 = space

could be a temporary solution.

Could be possible - I've experienced something similar with a
nonworking left shift key, or keys stuck in "control mode".
A bit "hammering" on the keyboard and some focus-shifting
solved the problem. It does happen once a few months and is
not predictable. Maybe some USB issue? Polling?

So switching over from one system to another does keep the
problem... maybe a mechanical or electrical problem caused
by the keyboard?

In any case, try to check with "xev" and see what - IF - really
happens when pressing keys.

I can recommend the Sun USB keyboard (I have model 6 here, but
model 7 should be fine, too). It's not IBM clicky quality, of
course. It's not clicky at all. But it's very comfortable and
feels still good in use. The 2x5 plus 1 extra keys on the left
and the 4 on the right are wonderful add-ons - fully programmable
and usable (I use them for window sizing, rolling, focusing,
and starting programs, as well as for volume control, lock
session, log out and shutdown); Compose is also a nice feature,
as well as the real Meta keys. You can get them for cheap
via eBay, for example. Pay attention to get a USB model - you
won't be able to use the regular serial ones (with the round
plug) on a PC.

This is the only USB keyboard I have. All other systems use
PS/2 IBM keyboards intendedly. Never had a problem with them,
even after Cola shower and disassembly. :-)
