If one wanted to use the menu to test DRAM, fiddle with cache settings,
play with chipset or pci registers, I think it's necessary to do that
before booting _any_ kernels, because the system may be flaky or not boot
at all. That's why I created a debug menu in linuxbios and not in linux.
I don't mean to imply that it's something everyone wants or should have.
But having the basic serial console input functions in the main cvs tree
would be nice-- then anybody can add their own menu for debugging (or
kernel parameters or whatever).
