Instead of doing this have you tried extending size of cmdbuf in ps2dev
structure to 8?

Thanks for suggesting this Dmitry.  I have now done that (and modified
cypress_ps2.c to set psmouse->state to the common PSMOUSE_CMD_MODE
instead).  This makes the psmouse-base linkage entirely clean, I
think...

And it *almost* works!  (Multitouch no longer works after suspend now).

Please see the forthcoming [PATCH v2] set, and thanks again for your
help.
