I think that the "nice high resolution" you see with GRML is presented by the
framebuffer. You only get this once the kernel starts to load. Until then
you get a very basic VGA screen, which the GRML may not show at all (in other
words the first visual impression of a LiveCD may be the framebuffer console).
With the latest versions CDs which use KMS (e.g. SystemrescueCD) the two
stages VGA-->framebuffer are visible if I recall correctly.
With regards to your own kernel, are you using KMS? If so, once the kernel
starts loading the KMS will dictate what resolution you get. If this is too
small to read (I think it will render the highest resolution possible) or you
want to set some custom resolution for whatever reason, then add nomodeset to
the kernel line in your grub.conf and also restore the vga=XXX line you had
