as they do with 2.4.21.

You don't get any kenel console output in Linux-2.4 or Linux-2.6 if console= is not specified and -nographic is used. This because the VGA controller is still precent according to the PCI BIOS, just not emulated. Because the Linux kernel finds the VGA controller it automatically selects this as the kernel console.

If you compile your kernel without VGA console support then specifying console= is not required, as the kernel will then automatically select the serial console as this is the first available console device the kernel knows about.
