FWIW, this can be done with relatively low overhead by creating a miscelaneous character device, and just using write() to write in the arguments. This is a bit worse than passing things through registers, but doesn't seem all that bad.
Nonetheless, having some entries in the syscall table that are designated as "dynamically allocatable" would be a nifty trick. If the kernel managed these, modules coluld safely grab a few at load time, and then declare which indices to use via a /proc file.
