Unfortunately, that doesn't work for me. I tried two combinations
(with unpatched driver of course):

(1) just pkill commands before /usr/bin/logger:
the laptop doesn't suspend at all after closing the lid; after opening
the lid, I got just frozen screen, non-responsive machine and not a
single line in Xorg log;

(2) pkill commands with vidcontrol, kern.vt.suspendswitch set to 0:
the laptop doesn't suspend after closing the lid; after opening, the
screen is switched to console 1; after pressing Alt+F9, I the machine
gets frozen. I found this in the log:

[  2678.788] (II) AIGLX: Suspending AIGLX clients for VT switch
[  2678.788] (WW) intel(0): drmDropMaster failed: Unknown error: -22

Anyway, your original patch works perfectly. After two months and
hundreds of suspends/resumes (sometimes 10-20 without powering down),
it works without a single issue. Thanks for making my life easier. :)
