<video/macmodes.h>:

| #define CMODE_8                 0       /* 8 bits/pixel */
| #define CMODE_16                1       /* 16 (actually 15) bits/pixel */
| #define CMODE_32                2       /* 32 (actually 24) bits/pixel */

So please try `cmode 1' instead of `cmode 16'.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
