kernel ignores kenv comconsole_speed?

[Stefan Bethke]

Am I doing something wrong, or is this a bug?  (This is on a stable  
from yesterday.)

I have -DS115200 in /boot.config, and boot and loader are happily  
using this speed. However, the kernel appears to be hardwired to 9600.

After boot, it's still at 9600:

# stty </dev/ttyd0
speed 9600 baud;
lflags: -icanon -isig -iexten -echo
iflags: -icrnl -ixon -ixany -imaxbel -brkint
oflags: -opost
cflags: cs8 -parenb clocal
# sysctl machdep.conspeed
machdep.conspeed: 9600

However, comconsole_speed is set correctly:
# kenv comconsole_speed
115200


I've recompiled my kernel with options COMSPEED=115200, and that  
fixed the issue for now, but shouldn't the kernel pick up the console  
speed from the kenv instead of using the hard-coded value?  Since  
machdep.conspeed is a sysctl, you can only change it after boot,  
which is kind of inconvenient...
