I've seen this happening when the BIOS also tries to talk to the  
serial port at the same time. Try changing the BIOS to stop doing  
console redirection once it starts booting, or replace boot0sio with  
boot0, and change boot(8) and loader(8) to only use the serial or BIOS  
console, but not both.

Since I don't dual-boot anymore, I've replaced boot0 with a standard  
MBR, and start off with boot(8) on all machines.


HTH,
Stefan
