Comment (by bonefish):

 Just extending the `vregs` structure will break binary compatibility
 (there's the `_reserved_1` which can and should be used, but obviously
 that isn't enough). You'll also have to introduce a binary compatible
 version of the structure (`vregs_beos`) and adjust the
 x86_signal_frame_function_beos() function (cf.
 src/system/kernel/arch/x86/x86_signals_asm.S, and
 src/system/kernel/arch/x86/asm_offsets.cpp for the assembly offset/size
 macros).
