Hi,
	We have this problem as well. I think the best solution for this
is to write a program that uses the /proc/efi interface. Another way of
doing this would be to write an EFI program. Attached is a program
fragment that, I think, with some work could set the speed (used code from
libtty from intel efi toolkit). We hope to not just set the speed of the
console output of the kernel but to have POST messages/efi console-
redirection running at a slower speed as well.

Are there any EFI experts who have comments on this? Do the new values in
the SERIAL_IO_MODE structure get updated in nvram so the redirection speed
is preserved across reboots?
