svgalib has support for this (man vga_ext_set, look for CLUT8), but most
drivers, including chips.c driver does not support this. Adding this
support should not be hard, but the program won't work as expected on
most video cards.

There is no interrupt support (that would require kernel support), but
there is the vga_waitretrace() functions (which does busy-waiting for
the retrace).
