Use a barometric fuse.
Don't need a mobile phone -- use a remote desktop connection via 801.b/g and a USB actuator to trigger the device. On-board Wi-Fi is not required, a peer-to-peer connection would work just as well.
It's not exactly rocket science, rather just a matter of time before the bad guys put something like that together. The suicide bomber would just be sitting in his seat playing solitaire on his other laptop.
