Actually, I can bypass this issue by enabling acpi(4):

ipmi0: <IPMI System Interface> port 0xca2,0xca3 on acpi0
ipmi0: KCS mode found at io 0xca2 on acpi
ipmi1: <IPMI System Interface> on isa0
device_attach: ipmi1 attach returned 16
pmtimer0 on isa0
ipmi1: <IPMI System Interface> on isa0
device_attach: ipmi1 attach returned 16

However, the driver fails right after with:

ipmi0: Timed out waiting for GET_DEVICE_ID

and thus never complete its startup... :(
