Hello.
Currently, gpm incorrectly setup mouse sample rate and this affected to 
mouse type detection.

Long description:
When mouse type set to 'autops2' gpm attempt to detect mouse type. Before
request identification from mice, gpm try set sample rate, but incorrectly.
gpm write two byte command and read ONLY one ACK from mice but when command
is two byte length - should read two ACK's (one from command, one from data).
Missed (unreaded) ACK stay in mice buffer and read_mouse_id() read ACK (0x0FA)
instead of mice ident (0x04) byte.

Attached patch fix this problem.
