[syslinux] vesamenu requirement

[Giampaolo Bellini]

Dear listener

 I'm having problem trying to setup a 640x480 image background with latest
syslinux...
 the system start correctly but graphics is not shown at all... only text is
visible...

 are there minimum requirements for a graphic extlinux background ?

 CPU is a Vortex86Sx (with no math processor) at 300MHz, 128MB RAM
 video card is a XGI Volari Z9s with 32MB RAM

 is there a way to retrieve more debug info from vesamenu.c32 ?

     thanks

            Giampaolo
