do not limit kernelpercent IFF *imagemaxmb= is used on a cpu server the heuristics that limits kernel memory on a cpu server to a fixed amout (64MB + size for page tables) makes using devdraw impractical. if *imagemaxmb= is specified, we can assume that the draw device will be used so we want to get a reasonable amount (30% default) of kernel memory.
