The logs you posted show the i8042 controller responsive when SeaBIOS
starts talking to it. So, I wonder if it's the keyboard that is still
powering up (instead of the superIO). (Of course, if the EC contains
both the keyboard and superIO, then this is irrelevant.)

Oh, okay. The logs you posted show this option disabled.
When this option is enabled, the "init ps2port" message should appear
before the VGA init. It should also eliminate any wait at the boot
prompt, as the boot menu delay should overlap with your hard drive
