VESA bios extensions don't have nothing to do with VESA Local Bus (VLB). The first ones are code to access SVGA modes and the last one is a type of bus like ISA, PCI, etc.

Ok,

But with which Command line and where activate i the VESA in the
DosBox 0.63, i don´t found it in the Forum.
Or is it usefull to use the CVS Bulid with the DosBox 0.63?

CVS builds have better VESA support I believe, so you could try one of those. I'm not sure it will speed your game up though - indeed, VESA modes were often used for higher resolution, rather than more speed. Setting Core=Dynamic in dosbox.conf, and messing with cycles and frameksip is more likely to help.

You don't need any command to activate VESA. It is used automatically when detected (if all goes well). Just grab a cvs version.
