Cc:ing the gpm list.

Gpm complains about this:
/home/jhd/gpm-1.19.4/gpm[4970]: imps2: Auto-detected unknown mouse type 4,
 assuming standard PS/2

This explains the "wrong protocol" behaviour.
If type 4 should be taken care of by gpm or 4 is a bad value from mousedev
seems to be the question.

The "old" initialization was just
write(1, "\363\310\363d\363P", 6)
 (AUX_SET_SAMPLE 200, AUX_SET_SAMPLE 100, AUX_SET_SAMPLE 80)
a nanosleep and
write(1, "\366\346\364\363d\350\3", 7)
 (0xF6 AUX_SET_SCALE11, AUX_ENABLE_DEV, AUX_SET_SAMPLE, 100, AUX_SET_RES, 3)


The new one is more elaborate and reads type 4 from the mousedev.
 (AUX_ENABLE_DEV, AUX_SET_SAMPLE, 100,
  AUX_ENABLE_DEV, AUX_SET_SAMPLE, 100,
  AUX_SET_SAMPLE, 200, AUX_SET_SAMPLE, 100, AUX_SET_SAMPLE, 80,
  AUX_SEND_ID,
  AUX_SET_SCALE11, AUX_ENABLE_DEV, AUX_SET_SAMPLE, 100, AUX_SET_RES, 3)

(probably a lot of unnecessary info again :-):
