This patch adds more information to the vbeinfo output, including the
video adapter VBE version, total video memory, and the color layout of
each video mode.

Thanks for the patch. In it went with a slight modification.

0x04 and 0x06 as used on memory model at least. There might be something

OK, I have replaced those and added the other VBE constants for those
fields. Even though many of the values are not currently used, it
seems to help document the other possible values and uses of the field.
Attached are both a full patch, and an incremental patch against the
first version.
Regards,
Colin

This refinement is against current SVN head. It introduces the VBE
mode info field constant values into vbe.h and these are used instead
of the magic numbers in vbeinfo.c.
