On x86, the combo is alt-sysrq, so shift can theoretically be added.

Just tested on a PS/2 port attached keyboard and it doesn't go
through.  I'm not sure where this is getting lost but given that
people sometimes have to use ctrl too to invoke sysrq, throwing in
shift makes it a four key combo which is likely to be over the
rollover capabilities of most keyboards.  It doesn't seem like a good
path to follow to me.  :(
