Possible bug in 2.4.19 ps/2 handling?

As I already posted 3 days ago I had severe trouble getting my mouse going on my new system... now I recompiled the whole system with gcc 2.95.3 instead of 3.2 and switched back to kernel 2.4.18 and that solved the problem. Neither using gcc 3.2 with kernel 2.4.18 nor using gcc 2.95.3 with kernel 2.4.19 did work. Both times pressing numlock killed the mouse and restarting gpm afterwards killed the keyboard. Just wanted to tell you in case this is indeed a kernel problem...
