  My understanding is the emgd kernel driver need to allocate memory
  dynamically, and the vmalloc=256MB parameter ensures enough will be
  available for the driver.
 
 OK, this explains the change to vmalloc.
 
 Why the change of vga=current and the drop of video=vesafb ?

Darren,
   Good catch. I changed this for cleanup, but now I see that it affects the 
splash screen. So I will resend the commit by dropping these extra changes.

Thanks,
Nitin
