You shouldn't need the vga= line for a paravirtualised kernel.  My kernel is 
configured with video= set to "video=xenfb" to tell it explicitly to use the 
Xen Framebuffer.  There isn't a vesa framebuffer available to a paravirt

I wanted to make sure that would work first!  Now we need to add to it...

Add "console=tty1" to your kernel command line.  This should tell the OS to 
output boot console output to tty1, which should display on the framebuffer 

Does that help?
