Actually only this will work:
ifconfig_vlan0_name="VLAN01"
ifconfig_VLAN01="inet 10.137.99.4 vlan 1 vlandev sk0"

One thing I noticed was VLAN01 could not be called something more
descriptive like VLAN-FOO since then the startup scripts went bananas
leaving my console in an ifconfig loop.
There was a patch from bart <bart at convex.ru> that he posted to
net@ adding possibility to add an ASCII description to devices the same
way Cisco does. 
Was it ever conserned as a commit candidate?
