Yes this is what I was experiencing.

Background info. I had put load commands for ipfw modules into 
/boot/loader.conf to test if this would work with a kernel that has 
vimage compiled in. The boot process would start normally and progress 
to the point where the usb messages get displayed and them the system 
would freeze up becoming unresponsive.

Figured I would just reboot and go in single user mode and remove the 
statements from loader.conf. But no matter what I tried the boot menu 
would no go into single user mode.

The solution was to take a testing disk that had 9.1-rc3 on it and cable 
it as master and the original disk as slave. In this configuration the 
system booted correctly and I mounted the slave and corrected 
loader.conf. Recabled the original disk as master and was back in 
business.

I think that because the ipfw modules were loaded before the boot 
process got to the boot menu is what caused the boot menu to not 
function correctly. Don't see a PR in this case.

Thanks to all who replied.
