Hi LaMont,
as we would like to use the new agetty -s option in systemd, please
consider packaging a newer git snapshot including [1] and [2] or
cherry-picking those two commits for the current version in unstable.
I've attached a squashed and refreshed patch based on those two commits
for your convenience.
Cheers,
Michael

agetty: add -s to reuse existing baud rate
For example:
/sbin/agetty -s /dev/ttyS0 9600
will reuse the speed the kernel configured on the port. If the setting
from kernel is useless (tty returns BREAK character) then the baud
rate from command line (9600) is used.

agetty: fix -s option (baud rate setup)
The problem is pretty visible in strace output:
broken version:
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B115200 opost isig icanon echo
...}) = 0
[...]
ioctl(0, SNDCTL_TMR_START or TCSETS, {B0 -opost -isig -icanon -echo
...}) = 0
^^^
fixed version:
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B115200 opost isig icanon echo
...}) = 0
[...]
ioctl(0, SNDCTL_TMR_START or TCSETS, {B115200 -opost -isig -icanon
-echo ...}) = 0
