I would think so!

The patch that fixed the issue with the key release events was this -
I submitted it to Alan who then put it into ac and then it went into
2.4.x...

Details: http://www.informatik.uni-freiburg.de/~leibl/lol/

Patch excerpt:

+ /* The following 'if' is a workaround for hardware
+ * which sometimes send the key release event twice */
+ unsigned char next_scancode = scancode|up_flag;
+ if (up_flag && next_scancode==prev_scancode) {
+ /* unexpected 2nd release event */
+ } else {
+ prev_scancode=next_scancode;
+ put_queue(next_scancode);
+ }

I haven't checked if 2.6.0 already has this!
