Forgot to switch to graphics mode before writing to the VBE framebuffer.

Tried to debug why VGA wasn't working. Forgot to remove the drawing statements.

First time my os crashed, big one too!
I was testing normal - c code and I forgot that doing puts(i); Prints that location in memory, so I dumped my kernel into console memory. Then think it dumped GRUB into console memory.
Code:
for(false)
{
   puts(i);
   i++;
}

I don't know if this counts as 'crazy', but for some reason the console default color messed up and now text is showing up pink, unless I specify another color.

Hehe, cute. Please let us know what caused this, once you find it.

I suspect it's the Log() function, which is very similar to printf... to print colored text, it changes the default color, and then it restores it at the end... for some reason the restore part goes wrong...

Update: Apparently, that was the problem... A few minor edits, and everything seems to work now.

Tried to enable paging; apparently the kernel loved that!
I think I copied the page tables into graphics memory somehow... hehe lets try again :)

Turns out it's actually a bug with QEMU's Cocoa frontend, it works fine anywhere else :P
