In theory - this could work. The Linux IR project folks have had success with using laptop IR ports as remote control devices, but the range is short, and the viewing angle rather limited too.. I've toyed with this myself, and written some code (...) (24 years ago, 28-Aug-01, to lugnet.robotics.rcx)

Should be OK, the light sensor mode works by measuring the resistance of an external LDR (light-dependant resistor), so it is designed to cope with the equivalent short-circuit of a stalled motor.. the only problem might be the back-emf generated if (...)
