Chrome can't connect to bus on RPI3 running -current

[bob prohaska]

Www/chromium finally compiled on a Pi3 running -current. 
The system is presently at (GENERIC) #5 r355919: Sat Dec 21 09:51:45 PST 2019

Chrome can be run (slowly!) across a network and seems to work, but
the controlling terminal is littered with

bob at www:~ % chrome

and that's just opening the home page 8-)

/etc/rc.conf contains
hald_enable="YES"
dbus_enable="YES"

Both hald and dbus are visible to pgrep:
bob at www:~ % pgrep dbus
1250
1254
1255
955
bob at www:~ % pgrep hald
1127
1131
1100
1101
1103

Are there some other services that need to be turned on?

Thanks for reading,
