Yes, looks like that's it. After downgrading to udev 0.125 I get:

import_uevent_var: import into environment: 'DRIVER=dasd-eckd'
import_uevent_var: import into environment: 'CU_TYPE=3990'
import_uevent_var: import into environment: 'CU_MODEL=C2'
import_uevent_var: import into environment: 'DEV_TYPE=3390'
import_uevent_var: import into environment: 'DEV_MODEL=02'
import_uevent_var: import into environment: 'MODALIAS=ccw:t3990mC2dt3390dm02'
udevtest: looking at device '/devices/css0/0.0.0005/0.0.0121' from subsystem 'ccw'
wait_for_file: file '/sys/devices/css0/0.0.0005/0.0.0121/online' appeared after 0 loops
udevtest: run: '/sbin/hwup -A -D /devices/css0/0.0.0005/0.0.0121 ccw 0.0.0121'
udevtest: run: 'socket:@/org/kernel/udev/monitor'

Note that those 'import_uevent_var' messages are not displayed with 0.140,
but that may be as expected or unrelated.
