Display VESA graphics modes, with their mode IDs, in the vga=ask
menu. Most VESA mode numbers are platform-dependent, so it helps to
have an easy way to display them.

There exists at least one card, Trident TVGA8900CL (BIOS dated 1992/9/8)
which clobbers DS when "scrolling in an SVGA text mode of more than
800x600 pixels." Although we are extremely unlikely to run into that
situation, it is cheap insurance to save and restore DS, and it only adds
a grand total of 50 bytes to the total output.

Video mode probing for the new x86 setup code. This code breaks down
different drivers into modules. This code deliberately drops support
for a lot of the vendor-specific mode probing present in the assembly
version, since a lot of those probes have been found to be stale in
current versions of those chips -- frequently, support for those modes
have been dropped from recent video BIOSes due to space constraints,
but the video BIOS signatures are still the same.
However, additional drivers should be extremely straightforward to plug
in, if desirable.
