My Dell “Precision M4500” notebook suffers similar (same?) problem.  So far 
I could not find a solution better than this:  e.g. Alt-Fn-SysRq-s

press and hold Alt
press and hold Fn
press and leave F10|SysRq
leave Fn
press and leave s
leave Alt

Several months ago a LKML user claimed, his cat had managed to press 
Alt-Fn-SysRq-c on his Dell Latitude notebook with similar keyboard, and provided 
photos showing the kernel crash message ;)
