Well, there is currently another breakage on Zaurus. But it improves the
situation.
(Note: Your patch has bad file path. I'll agree with such change after
this fix.)

Test report on Zaurus
(serial hardware itself is in undefined state after resume):

                                       before  after
login:                                   OK     OK
console:                               broken broken
console + login:                         OK     OK
console + no_console_suspend:          broken broken
login + no_console_suspend:              OK     OK
console + login + no_console_suspend:  broken   OK
