SEISA retroilluminated keyboard - ctrl & alt doesn't work

Hello!

First of all, I apologize for my horrible english, It's not my mother language.

Lets get to the point: Last week I bought a SEISA retroilluminated keyboard (It's a very cheap make).

I've set the corresponding keyboard layout, but noticed something weird, most of the bottom line keys are recognized as shift (Ctrl, Alt, window$ key, AltGr, RightCtrl; just the keys 'space' and 'context menu' work well), that means, when I push those keys I get a shift instead of the key it should be.
Tested it on window$ and keys do work well, so looks like a configuration issue.

What should I do in this case? Make a new keyboard layout for this keyboard?

Edit: some sad information, all named keys send keycode 42

[a@sulfur ~]$ sudo showkey 
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode  42 press
keycode  42 release
keycode  42 press
keycode  42 release
keycode  42 press
keycode  42 release
keycode  42 press
keycode  42 release
keycode  42 press
keycode  42 release
keycode  42 press
keycode  42 release
[a@sulfur ~]$ 

Thanks in advance!
