Grub2, vbeinfo not listing all supported resolutions?

Hi, for some reason vbeinfo doesn't list the full range of supported resolutions for my display (1024x600 to be exact) which is probably also why I can't use that resolution in grub2 when booting.

So my question is, is there a way to make it support this resolution and if yes how? Because when I boot up right now it goes from (what I assume to be) 640x480 (BIOS) to 800x600 (Grub2) to 1024x600 (Linux) which is somewhat annoying, I would prefer to already have the full 1024x600 resolution in Grub2 if possible.

Re: Grub2, vbeinfo not listing all supported resolutions?

Well, the 915reshack made it possible for me to display the 1024x600 resolution but if possible I would like to avoid having to revert to such a hack.

Could it be due to the fact that I don't have early KMS enabled? I initially didn't have any modules in the mkinitcpio.conf listed but even after adding i915 as described it still lists the same resolutions (I have a GMA 3150 chip in my laptop).

However I'm also unable to run any games from the console (example error message is "Couldn't initialize SDL: No available video device", it works when I launch from the x server though), so maybe something else is the problem?

Perhaps the driver is not loading correctly before starting the x server or something like that, is there a way to check if the driver is running correctly?
Maybe I should also mention that this is a pretty fresh installation so not much has been custom-configured yet.
