Here are some uneducated thoughts:

1. Make serial port polled instead of interrupt driven?  Majority 
of traffic is output that will be buffered.

2. Increase serial port buffer size?  Perhaps problem is so much 
serial output that buffer fills up and blocks.

3. Make serial port faster?  Would help drain buffer quicker.  
115200 baud is routine, I've seen 460800 baud being used for 
embedded Linux on short cables.

4. Is there a way to have a remote console via ethernet?  Won't 
help with BIOS settings, but would remove serial port issues.

5. Use different serial port hardware (USB serial dongle, PCI
multiport card, etc) for console.  Switch serial cable to do BIOS
settings if need be.

What BIOS do you have that is serial configurable?  I'm always on 
the lookout for that.
