If you only want standard vga modes, then those lines are ignored
anyway. The vga modes have specific refresh rates, and any vga monitor
is supposed to support them.
There is no autodetection of those parameters. To add support for this,
all drivers need to have DDC support, and an EDID interpreter shouldbe
incorporated in svgalib.
