REMCONS broken after upgrading to 9.1-RC2

Hello all, 

I had a working REMCONS setup on Freebsd 9.0 for remote access on my HP DL165 G7 (LO100i). I recently built and installed 9.1-RC2 on a separate dataset on this machine's ZFS pool and merged in my existing configuration from 9.0. 

On 9.1-RC2 I no longer get a login prompt. However, I still do have access to the loader prompt and can see the kernel boot messages on the serial console. I built my GENERIC kernel and world using clang with default flags. I see that the kernel identifies the serial port getty has spawned on the port.

# dmesg |grep uart 
uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 
uart0: console (115200,n,8,1) 

# ps axl|grep ttyu0 
 0 5405    1   0  20  0  11996  1416 ttyin    Is+  u0    0:00.00 /usr/libexec/getty std.115200 ttyu0 

Here are the relevant configuration bits I copied over from 9.0 setup that works: 

/etc/ttys: 
ttyu0   "/usr/libexec/getty std.115200" screen-256color on secure 

/boot/loader.conf: 
boot_multicons="YES" 
boot_serial="YES" 
comconsole_speed="115200" 
console="comconsole,vidconsole" 

# kenv |grep uart.0 
hint.uart.0.at="isa" 
hint.uart.0.flags="0x10" 
hint.uart.0.irq="4" 
hint.uart.0.port="0x3F8" 

Have there been any changes to the serial console setup in 9.1 or has anybody else experienced similar problems?
