I experience this problem as well. My solution was to grab a com.c and 
comreg.h out of an older kernel and patch them in. It worked fine after

If you want my com.c and comreg.h that I hacked up with the older code and
newer isa attach structure let me know.

Also, so that you can get things done, a "stty 9600" to slow things down
a bit fixes things for that session. (May need to do "stty -f /dev/tty00 9600"
[substitute your device] locally to set the local tty.)

Even though I had time to hack up the old com.c to work (!) I haven't had
time to figure out anything else about why it happens.. anybody else have
