If you are meaning 2.4.7 and not 2.4.17 I have found the
reason while looking in pc_keyb.c:
static inline void handle_mouse_event(unsigned char scancode)
{
if (mouse_reply_expected) {
...
}
else if(scancode == AUX_RECONNECT){
queue->head = queue->tail = 0; /* Flush input queue */
__aux_write_ack(AUX_ENABLE_DEV); /* ping the mouse :) */
return;
}
So whenever the touchpad sends 0xAA (AUX_RECONNECT) the kernel flushes the
queue. Thats why you must press a button when starting gpm, because the
mouse identification doesnt reach gpm.
It also the reason for your problems while using the touchpad because the
touchpad can send 0xaa and will get out of sync afterwards.

hmm, I dont believe the kernel version causes this.
