System: NetBSD bimota 1.2E NetBSD 1.2E (BIMOTA) #30: Tue May 13 23:32:51 JST 1997 koji@ducati:/mnt2/NetBSD/work/src-ufs-mod/sys/arch/i386/compile/BIMOTA i386


>Description:
	In current implementation, I can`t disconnect and recoonect
	ps/2 mouse during opening pms*. So I must restart X to use it
	again onse disconnected.

	And GlidePoint tapping feature is not supported in current
	implementation.

	I have modified pms driver for these problem on NetBSD/i386.
>How-To-Repeat:
	First, use ps/2 mouse and start X, then disconnect ps/2 mouse.

	Just move mouse, but your pointer never moves.
>Fix:
q
	Apply following patch
