This is a call to all devs! The 0.2.7 branch has a input bug that is currently listed as a blocker for the release. We have been unable to get ahold of tinus (the i8042prt author) to take a look at this particular bug. If anyone is capable and interested in fixing this, please contact myself or simply join #reactos and offer help.
