 I have this same problem in pfSense 2.0.1 (FreeBSD 8.1-RELEASE-p6). It
 seems that if I enter ddb using real (usb) keyboard, I can control it
 via serial console. Resuming execution will print more characters and
 stop. This can be repeated couple of times until entering ddb will
 cause what looks like a freeze where not even numlock works but
 repeatedly breaking will get me back to usable ddb.
 
 I have disabled all non-essential devices in bios (everything except
 usb and serial) and tried booting into single user mode.
