There is at least one implementation for x86 that uses the VGA directly (as the BIOS left it), getting it very soon. But you are right, PC's speciality is not to have a nice console. Anyways, you can use early_printk() in MIPS. You only need to put the setup of the early console sooner, as for you the setup is basically a NOP.
